SDL Legit Install on win 10 and Tradus 2015

Dear community,

I have a problem with the SDL Legit Plugin. I installed it successfully but it does not appear in the Welcome screen of Trados 2015. I also can not find it in the App list on Windows main menu. Neither can I find it in program files on C drive.

The SDL Plugin Management shows the plugin and I can uninstall it from there and that's all.

Please help me!
