Cannot start or uninstall DocNav

Jump to solution

Hello!

I'm unable to either start or uninstall DocNav on Windows 10 64-bit. When I start DocNav, I get the following error:

 

The application was unable to start correctly (0xc000007b). Click OK to close the application.

I cannot uninstall DocNav. The installation log file reads:

I've also tried to uninstall and reinstall Java to no avail. Please help!

I removed my entire C:\Xilinx directory (I only have DocNav installed on this PC) and Xilinx Design Tools from my Start Menu folder. Then I reinstalled DocNav 2019.2 from scratch. The same error appeared when I ran DocNav. When I tried to run the uninstaller, it stated that MSVCP140.dll was missing. A quick Google search indicated that I was missing or had a corrupted Microsoft Visual C++ 2015 Redistributable package. Once I installed this, DocNav launched just fine.

Hi @tonyle 

This looks like a compatibility issue. I would suggest a google search with the error message.

Which version did you download? How are you attempting to uninstall DocNav?


Cheers

I believe I'm trying to uninstall 2019.2 though I'm not certain since it won't run. I'm using the Uninstall DocNav link in the Windows start menu. The uninstall log reports the following:

Unfortunately the only relevant search result from Google is this forum thread. :-|
