How To Fix vcomp140.dll Missing And Other Errors
The safest way to fix these errors is to reinstall the related application – ie the antivirus software. This should reinstall the latest DLL files and fix any issues.
You may wish to uninstall the previous version first too – to be downloading to a ‘clean’ PC.\An alternative is to download the missing file from the Github project repository – although this is very technical and should only be done by a developer.
The other common fix, which we do not recommend, is to use one of the many DLL download sites. Adding the file may not fix the problem as DLL errors are often more complex than a missing file (even if that’s the immediate error that is flagged).
In addition the files on these sites are often out of date, or even contain viruses, which could also cause problems.
Therefore, we recommend reinstalling the application (ie Visual Studio) using the offending dll file to fix any vcomp140.dll error.
