You might experience issues such as these when you try to print from your Mac or print from your iOS device:
File Finder
- You can't see your printer from your device, or you get a message that no printers were found.
- You get a message that software for your device isn't available.
- You have some other printing issue related to the software on your Mac or iOS device.
For help with an error light or other error condition on the printer itself, check the printer's documentation or contact its manufacturer.
If your printer is AirPrint-enabled
If your printer is AirPrint-enabled for printing from your Mac or iOS device, just make sure that it's connected to the same Wi-Fi network used by the Mac or iOS device.1
If you still can't print, try any of these solutions:
- Restart your Wi-Fi router. Then restart your printer.
- Move your printer closer to your Wi-Fi router.
- Update your printer and Wi-Fi router with the latest firmware from the manufacturer.2
- Update the software for your Mac or iOS device.
If you're using a Mac and you still can't print, it might help to reset the printing system. Otherwise, contact the printer manufacturer for support.
If your printer isn't AirPrint-enabled
If you're printing from your Mac to a printer that isn't AirPrint-enabled:
- If your printer is connected to your Mac with a cable, disconnect the cable from your Mac.
- Turn off your printer.
- Get software updates for your Mac. Your Mac automatically downloads the latest software for most printers as part of these updates, so it's best not to install software from the printer manufacturer.
- Reconnect your printer to your Mac, if applicable.
- Turn on your printer and wait for it to finish starting up.
- Choose Apple () menu > System Preferences, then click Printers & Scanners.
- Select your printer in the list of devices.
If your printer doesn't appear in the list of devices in Printers & Scanners preferences, click at the bottom of the list, then choose the command to add a printer or scanner. The window that opens offers more ways to find and add a printer, such as by IP address:
If you still can't print, and your printer is connected via Wi-Fi:
- Restart your Wi-Fi router. Then restart your printer.
- Move your printer closer to your Wi-Fi router.
- Update your printer and Wi-Fi router with the latest firmware from the manufacturer.2
Reset the printing system
If the issue continues, reset the printing system on your Mac. This removes all printers and scanners—including their print jobs and settings—from Printers & Scanners preferences.
- Choose Apple menu > System Preferences, then click Printers & Scanners.
- While holding down the Control key on your keyboard, click anywhere in the list of devices.
- Choose “Reset printing system” from the menu that appears:
Remove printer drivers
If the issue continues on your Mac after resetting the printing system, take these final steps to remove any currently installed printer drivers. These steps don't apply to AirPrint printers.
- From the menu bar in the Finder, choose Go > Go to Folder. Type
/Library/Printers/
and click Go. - The Printers folder opens. Choose Edit > Select All, which selects all items in the Printers folder.
- Choose File > New Folder with Selection, which puts all of the selected items into a new folder named New Folder With Items. To save storage space, you can delete this folder.
If the issue continues, contact the printer manufacturer for support.
1. In corporate environments, DNS records can be configured to allow AirPrint-enabled printers to appear across other networks instead of just the network used by the device you're printing from. You can also use configuration profiles in iOS to set up AirPrint printers.
2. Firmware updates—such as for AirPort base stations—update the software on the printer or router, not the software on your Mac or iOS device. If the latest firmware from the manufacturer is several years old, the manufacturer might have stopped supporting or updating your device. If so, you might need a more up-to-date printer or router.

Below is a list of troubleshooting steps to resolve your Error RPC problems. These troubleshooting steps get progressively more difficult and time consuming, so we strongly recommend attempting them in ascending order to avoid unnecessary time and effort.
Please Note: Click the [ ] image to expand the troubleshooting instructions for each step below. You can also click the [ ] image to hide the instructions as you proceed through each step.
Step 1: Repair Registry Entries Associated with Error RPC |
Manually editing the Windows registry to remove invalid Error RPC keys is not recommended unless you are PC service professional. Incorrectly editing your registry can stop your PC from functioning and create irreversible damage to your operating system. In fact, one misplaced comma can prevent your PC from booting entirely! Because of this risk, we highly recommend using a trusted registry cleaner such as WinThruster [download] (Developed by Microsoft Gold Certified Partner) to scan and repair any Error RPC-related registry problems. Using a registry cleaner [download] automates the process of finding invalid registry entries, missing file references (like the one causing your RPC error), and broken links within the registry. A backup is automatically created before each scan, with the ability to undo any changes in a single click, protecting you against the possibility of PC damage. The best part is that repairing registry errors [download] can also dramatically improve system speed and performance. Caution: Unless you an advanced PC user, we DO NOT recommend editing the Windows registry manually. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows. We do not guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. To manually repair your Windows registry, first you need to create a backup by exporting a portion of the registry related to Error RPC (eg. Avast! Antivirus):
The next steps in manually editing your registry will not be discussed in this article due to the high risk of damaging your system. If you would like to learn more about manual registry editing, please see the links below. We do not claim any responsibility for the results of the actions taken from the content linked below - complete these tasks at your own risk. Windows XP Windows 7 Windows Vista |
Step 2: Conduct a Full Malware Scan of Your PC |
There is a chance that your RPC error could be related to a malware infection on your PC. These malicious intruders can damage, corrupt, or even delete Runtime Errors-related files. Furthermore, there's a possibility that the RPC error you are experiencing is related to a component of the malicious program itself. Tip: If you do not already have a malware protection program installed, we highly recommend using Emsisoft Anti-Malware (download here). They offer a malware removal guarantee that is not offered by other security software. |
Step 3: Clean Out Your System Junk (Temporary Files and Folders) With Disk Cleanup (cleanmgr) |
Over time, your computer accumulates junk files from normal web surfing and computer use. If this junk isn't occasionally cleaned out, it can cause Avast! Antivirus to respond slowly or provides an RPC error, possibly due to file conflicts or an overloaded hard drive. Cleaning up these temporary files with Disk Cleanup might not only solve your RPC error, but can also dramatically speed up the performance of your PC. Tip: Although Disk Cleanup is a wonderful built-in tool, it will not completely clean up all of the temporary files on your computer. Other programs that you frequently use such Microsoft Office, Firefox, Chrome, Live Messenger, and hundreds of other programs are not cleaned up with Disk Cleanup (including some AVAST Software s.r.o. programs). Because of the shortcomings of the Windows Disk Cleanup (cleanmgr) tool, we highly recommend using a specialized hard drive cleanup / privacy protection software such as WinSweeper [download] (Developed by Microsoft Gold Partner) to clean up your entire computer. Running WinSweeper [download] once per day (using automatic scanning) will ensure that your computer is always clean, running fast, and free of RPC errors related to temporary files. How to run Disk Cleanup (cleanmgr) (Windows XP, Vista, 7, 8, and 10):

Step 4: Update Your PC Device Drivers |
RPC errors can be related to corrupt or outdated device drivers. Drivers can work one day, and suddenly stop working the next day, for a variety of reasons. The good news is that you can often update the device driver to fix the Error RPC problem. Finding the exact driver for your Error RPC-related hardware device can be extremely difficult, even directly on the AVAST Software s.r.o. or related manufacturer's website. Even if you are experienced at finding, downloading, and manually updating drivers, the process can still be very time consuming and extremely irritating. Installing the wrong driver, or simply an incompatible version of the right driver, can make your problems even worse. Because of the time and complexity involved in updating drivers, we highly recommend using a driver update tool such as DriverDoc (Developed by Microsoft Gold Partner) to automate the process. DriverDoc updates all of your PC device drivers, not just those associated with your RPC error. DriverDoc's proprietary One-Click Update™ technology not only ensures that you have correct driver versions for your hardware, but it also creates a backup of your current drivers before making any changes. Maintaining a driver backup provides you with the security of knowing that you can rollback any driver to a previous version if necessary. With updated device drivers, you can finally unlock new hardware features and improve the speed and performance of your PC. Please Note: Your Error RPC may not be related to hardware driver problems, but it's always a good idea to ensure all of your PC device drivers are up-to-date to maximize PC performance. |
Step 5: Utilize Windows System Restore to 'Undo' Recent System Changes |
Windows System Restore allows you to 'go back in time' with your PC to help fix your Error RPC problems. System Restore can return your PC's system files and programs back to a time when everything was working fine. This can potentially help you avoid hours of troubleshooting headaches associated with RPC errors. Please Note: Using System Restore will not affect your documents, pictures, or other data. To use System Restore (Windows XP, Vista, 7, 8, and 10):
|
Step 6: Uninstall and Reinstall the Avast! Antivirus Program Associated with Error RPC |
If your RPC error is related to a specific program, reinstalling Avast! Antivirus-related software could be the answer. Instructions for Windows 7 and Windows Vista:
Instructions for Windows XP:
Instructions for Windows 8:
After you have successfully uninstalled your Error RPC-associated program (eg. Avast! Antivirus), reinstall the program according to the AVAST Software s.r.o. instructions. Tip: If you are positive that your RPC error is related to a specific AVAST Software s.r.o. program, uninstalling and reinstalling your Error RPC-related program will likely be the solution to your problem. |
Step 7: Run Windows System File Checker ('sfc /scannow') |
System File Checker is a handy tool included with Windows that allows you scan for and restore corruptions in Windows system files (including those related to Error RPC). To run System File Checker (Windows XP, Vista, 7, 8, and 10):
|
Step 8: Install All Available Windows Updates |
Microsoft is constantly updating and improving Windows system files that could be associated with Error RPC. Sometimes resolving your Runtime Errors problems may be as simple as updating Windows with the latest Service Pack or other patch that Microsoft releases on an ongoing basis. To check for Windows Updates (Windows XP, Vista, 7, 8, and 10):
|
Step 9: Perform a Clean Installation of Windows |
Caution: We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve Error RPC problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately (download a highly-recommended backup solution) to protect yourself from permanent data loss. This step is your final option in trying to resolve your Error RPC issue. Reinstalling Windows will erase everything from your hard drive, allowing you to start again with a fresh system. Furthermore, a clean install of Windows will also quickly clean out any and all 'junk' that has accumulated over the normal usage of your computer. Please Note: If RPC errors still persist after a clean install of Windows, your Runtime Errors problem MUST be hardware related. If that is the case, then it is likely you will need to replace the associated hardware causing the RPC error. |
