DLL problem

Anonymous
Not applicable
When I want to start AC13, warning window appears: "The application or DLL C:\Program Files\Graphisoft\ArchiCAD 13\Tdx.dll is not a valid Windows image. Please check this against your installation diskette."
I didn't find the file on my installation CD.
Untill now, everything worked properly.

You may want to try two things:
1. Check for any virus.
2. Reinstall the program.
