Knight1231 Posted November 28, 2019 Share Posted November 28, 2019 I’m working on a Boot Camp Windows 8.1. Trying to go to Launchbox 10.7. But every time I try to open launchbox I get a CLR20r3 error. Launchbox 9 works tho. Any possible fix? Quote Link to comment Share on other sites More sharing options...
DOS76 Posted November 28, 2019 Share Posted November 28, 2019 probably need to update to .next framework 4.8 Quote Link to comment Share on other sites More sharing options...

Drakkorcia Posted December 2, 2019 Share Posted December 2, 2019 I had this same error and the fix was to run Windows update and download all critical updates if you're .net Framework was up to 4.8. Quote Link to comment Share on other sites More sharing options...
