Knight1231 0 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 Share this post Link to post Share on other sites

Drakkorcia 17 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 Share this post Link to post Share on other sites
