I can't open the program after installing the latest version of Trados 2021.

I have installed the latest version of Trados 2021 SR2 ( . Apperently the installation was OK but after that I cannot open the program anymore. The icon in the desktop has diappeared and I don't know what to do. I have new folders on my computer related to the program but I can't find a way to open it. I tried to open a package, for example, but it wouldn't open. So, the files are there, but the programm is not installed anymore. I don't understand it.

An easy way to solve my problem?

Do I need to desinstall the programm and install it again? If I have to do that, do I have to deactivate my lisence before desintalling? Or I just have to reset it?

Please I need your help!
