The file is most used in the “ActiveSync” feature of Windows to help communications between mobile devices and your PC. Although the rapi.dll file is a crucial part of the Windows OS, it’s continually causing problems & errors. If you’re seeing any sort of error caused by this file, you should look to fix the issue by using the steps outlined this tutorial.
The errors you’ll likely see from rapi.dll include the likes of:

- “Cannot find rapi.dll”
The way to fix this error is to repair the various problems that are causing it to show. Because the file is a “core” part of Windows, the likelihood of it being overwritten or damaged or low, but in order to repair the error – you need to be able to first look at the file itself and then any problems that Windows may have causing the issue.
The first step to fixing the rapi.dll error on your PC is to update your system. This can be done by either browsing to the Microsoft Updates website or by clicking onto the “Windows Update” program on your PC to update the program. This will allow you to download and install all the latest updates for your computer, which will basically remove any problems / bugs that Microsoft might have overlooked when they released the system. It can be a problem that your PC will have some sort of error leading to the messages you’re seeing, which an update could fix.
The second step to fixing the rapi.dll error is to then make sure the file is working correctly on your PC. This can be done by first making sure the rapi.dll file is present on your PC, and then ensuring it’s in the “C:\Windows\System32” folder of your computer. Not only will this allow your system to better read the file, but you may also wish to replace the file on your computer to enable Windows to read it properly.
Finally, you should also look to clean out any errors that the “registry database” may have inside. This is a big cause of DLL errors because of the way in which it stores a large list of the DLL files on your PC. Not many people even know what the registry is, and are certainly not aware that it’s actually one of the biggest causes of errors on your PC. The registry database stores all the files, settings and options which Windows uses to run, and is used continually to help your system run. Although the registry is continually being used to help your system operate, its list of DLL files often becomes damaged & corrupted – leading your computer to show the errors you’re seeing. To ensure this problem is not an issue, you should use a registry cleaner tool to fix the problems that may be inside the registry – which will boost the speed and reliability of your system again.
