Error while installing AS 4.12

Hello all,
I’ve had problem with AS because it didn’t open and I’ve deleted it and wanted to do fresh install. Now I’m getting this error.

What can I do?

The error code mentioned Technology Guarding.
How did you uninstall AS?

Try otherwise to uninstall Technology Guarding before installing AS.

I found solution. Deleted AS and codemeter. Downloaded Codemeter and installed. Then installed AS.
