Solved: Quixel SUITE 2.1.2 - Silent install - Version ID How?

Hi, I work for a school and I'm doing a silent install of the Quixel SUITE 2.1.2. The silent install part works correctly. But I discovered that when the SUITE is installed and working then I have no way to find out what version is installed!!! In fact, the only way, that I know of, is to launch the application and do "About". There's no registry key about the version of the SUITE and I couldn't find a single file with a file version. I need to identify which version is installed so that I can update correctly my computers when a new update is available. Anyone knows how I can do this?

Thanks in advance for the help!
