reinstallation of the trados 2017

Hi, everyone.

 

I used the trados 2017 trial version and deleted it before. And nowadays, I want to reinstall and activate the licensing version, but the software does not install on my computer. The window screen shows the completely installed sign but can not create the action icon to put on the activate code which I purchased on the main screen and the start menu either. Please help me to solve the problem.
