StaadPro v8i not starting

Hello,

We have several computers with StaadPro V8i. Since several days ago, when we try to open StaadPro we receive an error message: "The application failed to initialize properly (0xc0150002)".

After a search on Internet, I've seen the same error message for other programs, but the solution seems to be different for each program.

Thanks in advance for help.
