unable to open base camp after installation get error code 0xc000007b

same problem

Installed an older version and it works but not a permanent fix

was able to run legacy version 4.2.5 downloaded from here: https://www8.garmin.com/support/download_details.jsp?id=7161

.NET and DirectX reinstallations did not solve the issue on Windows 10

thanks for the advice! 

If 4.2.5 works, you can try updating BaseCamp to newest version. If .net 3.5 sp1 is missing, try installing it from microsoft.

Thanks BTLAAKE. I've tried that several times, but unfortunately with the same errormessage. And now I can't install 425 anymore either.  

Sorry I  made things worse.

In the past, users have found that the uninstall does not remove all traces of the software.  I would suggest contacting support for instructions to cleanup the registry (backup first) and any other folders/files for BaseCamp.  Hopefully that will get you back to a state where 4.2.5 will intall.

You are not to blame.

A very late response, sorry about that, but eventually I was able to solve the problem of error code 0x000007b by removing all installed Visual C++ files and then (after restarting PC) reinstalling the versions up to 2013 using a batch file (Visual-C-Runtimes-All-in-One, just search the internet). Maybe this will be of use for others with the same problem. 

This was the solution. Thank you very much.

glad it helped
