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. ![slika](https://europe1.discourse-cdn.com/brcommunity/original/2X/6/6996f220b2cf337c8be1b9acebd68d427f536952.png) What can I do? ---

The error code mentioned Technology Guarding. How did you uninstall AS? Try otherwise to uninstall Technology Guarding before installing AS. ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/e/ebfebd0b10cca72f98d978962005dce7256c1767.png) ---

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