WerFault.exe or WerMgr.exe Application Error
The instruction at the referenced memory could not read. Click on OK to terminate the program.
WerFault.exe and WerMgr.exe are system files located in the System32 folder. It is a part of the Windows error reporting system that collects and send error logs from your system, to Microsoft.
Microsoft Windows Error Reporting Service helps Microsoft and Microsoft partners diagnose problems in the software you use and provide solutions. Not all problems have solutions, but when solutions are available, they are offered as steps to solve a problem you’ve reported or as updates to install.
This error could occur if the file has got corrupted due to some reason. If you receive this error frequently, it could become quite irritating.
1] What you can do is to run System File checker to scan your PC for and repair your corrupted system files. Once the scan is completed, restart your computer.
2] The other option would be to run Windows Memory Diagnostic Tool.
Click on Restart now and check for problems and let the tool scan for and fix memory-related problems.
3] If this helps, good for you. If it does not then the best option for you would be to disable Windows Error Reporting Service.
WerSvc or Windows Error Reporting Service allows errors to be reported when programs stop working or responding and allows existing solutions to be delivered. Also allows logs to be generated for diagnostic and repair services. If this service is stopped, error reporting might not work correctly and results of diagnostic services and repairs might not be displayed.
To do this, Run services.msc. Locate Windows Error Reporting Service. Right click on in and select Properties. Change its startup type, from Manual to Disabled. Click OK and restart your computer.
This should help stop both type of errors, viz WerMgr.exe Application Error and WerMgr.exe Application Error.
You can also use the Windows Registry to enable or disable Windows Error Reporting Service.
