Question on VSIntegration.exe

I'm assuming you're following these instructions. https://support.smartbear.com/testcomplete/docs/working-with/integration/ms-vs/alm/install-integration-package.html

Basically, it seems that the VSIntegration package you're running can't find the visual studio version.  Question: What version of TC are you running?  Visual Studio 17 support wasn't added until TC 12.30 so if you're running a TC version prior to that, it's possible this is the source of your problem.
