Hello, Please note that i encounter systematically a crash when i try to launch WinToolKit 2.0.5651.42757 (maybe older versions too). I'm on Windows 7 x64 (up to date) .net framework 4.5.3 , then now 4.6 final (still crashs) In the Windows Event Viewer it seems to be related to "KERNELBASE.DLL", or after searching on the Internet maybe a .Net Framework issue.. I tried to open it in a testing Windows 10 x64 VM (with nothing special installed), it started without any problem. What can i do to run it on my Windows 7 ? Thx a lot for your hard work, i'm following you for a long time now, you're really talented ! Regards,
