I have ADC ver 3.3.2 and am wondering if it is compatible with Windows 10?
Yes, the 3.3.2 version works on Windows 10, but you will have to launch it using Run as Administrator after right click is used on the setup package. I have tried it and it works without errors. The same thing applies for when you launch the application for the first time. You can download version 3.3.2 through the download page at Software Informer. The link is posted below.
