Cause of Appmgmts.dll Errors
Appmgmts.dll errors are caused by situations that lead to the removal or corruption of the appmgmts DLL file.
How To Fix Appmgmts.dll Errors
Important: Do not download appmgmts.dll from one of those DLL download sites. There are many reasons why downloading a DLL file is a bad idea. If you need a copy of appmgmts.dll, it's best to obtain it from its original, legitimate source.
Note: Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the appmgmts.dll error.
If you suspect that you've accidentally deleted appmgmts.dll but you've already emptied the Recycle Bin, you may be able to recover appmgmts.dll with a free file recovery program.
Important: Recovering a deleted copy of appmgmts.dll with a file recovery program is a smart idea only if you're confident you've deleted the file yourself and that it was working properly before you did that.
Scan your entire computer for viruses and other malware. Some appmgmts.dll errors could be related to some kind of malware infection on your computer that has damaged the DLL file.
It's even possible that the appmgmts.dll error you're seeing is related to a hostile program that's masquerading as the file.
Execute the sfc /scannow command to replace a missing or corrupt copy of the appmgmts.dll file.
Important: This is the most likely solution to a missing or not found appmgmts.dll error. Please make every effort you can to complete this step after making sure your computer isn't infected with malware.
Use System Restore to undo recent system changes. If you suspect that the appmgmts.dll error was caused by a change made to an important file or configuration, and System File Checker didn't help, a System Restore should solve the problem.
Reinstall the program that uses the appmgmts.dll file. If the appmgmts.dll DLL error occurs when you use a particular program, reinstalling the program should replace the file.
This step is most useful for replacing DLL files that are not supplied by Microsoft but it could help with your appmgmts.dll problem if this program also provides a copy of the file and the previous troubleshooting ideas weren't successful.
Update the drivers for hardware devices that might be related to appmgmts.dll. If, for example, you're receiving a "The file appmgmts.dll is missing" error when you play a 3D video game, try updating the drivers for your video card.
Note: The appmgmts.dll file may or may not be related to video cards - this was just an example. The key here is to pay very close attention to the context of the error and troubleshoot accordingly.
Roll back a driver to a previously installed version if appmgmts.dll errors began after updating a particular hardware device's driver.
Install any available Windows updates. Many service packs and other patches replace or update some of the hundreds of Microsoft distributed DLL files on your computer. The appmgmts.dll file could be included in one of those updates.
Repair your installation of Windows. If the individual appmgmts.dll file troubleshooting advice above is unsuccessful, performing a Refresh, Startup Repair, or Repair Installation (depending on your version of Windows) should restore all Windows DLL files to their working versions.
Use a free registry cleaner to repair appmgmts.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid appmgmts.dll registry entries that might be causing the DLL error.
Important: I rarely recommend the use of registry cleaners. I've included the option here just in case it turns out to be helpful, in which case you could avoid the more difficult testing and last-resort options below.
Test your memory and then test your hard drive. I've left the majority of hardware troubleshooting to the last step, but your computer's memory and hard drive are relatively easy to test and are the most likely components to cause appmgmts.dll errors as they fail.
Perform a clean install of Windows. A clean install will erase everything and install a fresh copy of Windows. If none of the steps above correct the appmgmts.dll error, this should be your next course of action.
Important: To be clear, all the data on the drive you have Windows installed on will be deleted during a clean install so be sure to backup important files if you're able to. Obviously, make sure you've made every attempt possible to fix the appmgmts.dll error using a troubleshooting step prior to this one before you take on a clean install.
Troubleshoot for an unknown hardware problem if any appmgmts.dll errors persist.
A clean install of Windows is a fresh start on the software-side of the troubleshooting. So unfortunately, if that didn't work, your DLL problem must be hardware related.
The appmgmts.dll error message could apply to any program or system that might utilize the file on any of Microsoft's operating systems including Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.
