I believe Service pack 2 is required for it. Also Windows 7 is end of life and no longer supported by Microsoft, so i would suggest upgrading your OS if you are concerned about your security in any way.

C-Beats Posted May 7, 2021 Share Posted May 7, 2021 LaunchBox uses .NET Core 3.1 as of version 11.2 not Framework, and as Neil said you have to have SP2 installed to install those dependencies. Quote Link to comment Share on other sites More sharing options...
