I installed Cubase 11, didn't activate it, but I can not run 10 anymore

I installed Cubase 11. I didn’t activate it and I’m not going to do it.

Now I run C10 and have this error.

When I run Elicencer, I have this error

I am very angry and how do I fix this? :blush:

Ok, I have found the answer. It is “C:\Program Files (x86)\eLicenser\POS\SYNSOPOS.EXE” process that hanged and don’t allow to do anything. I killed it and it’s ok now.
