I installed CCC v1.1.2.4 and it no longer crashes but it didn't recognize that I had manually installed Lexington v21.11.0.25, so I had to let CCC install it again. I had even tried running CCC as administrator.
I have SONAR Platinum 64bit and 32bit installed, so I'm not sure if that causes any issues.
I have Windows 10 Pro 64bit
Winver says I have Version 1511 OS Build 10586.36
