What I have tried:

Activate as automatic SERVICES: ActiveX Installer (AxInstSV) an restart it
C:\WINDOWS\system32> sfc /scannow
C:\WINDOWS\system32> regsvr32 scrrun.dll

For a while in the same session it works fine, but suddenly the exception appears
I have been reading a lot about it, especially about the Reflection method, but I have not understood it.
I would greatly appreciate your help.

ScrRun.dll is the Windows Scripting Runtime. It has nothing to do with what your code snippet is doing.

My first guess for the problem is you wrote this code against a certain version of Office and that version, or a compatible version, is no longer installed on the machine.

Your tabs said VS2002, and that is a VERY OLD version of Visual Studio. The versions of the .NET Framework that version supported are no longer supported themselves.

If that's the case, I would imagine the code has to be updated and recompiled against newer versions of Office and .NET using a updated Visual Studio version.

If at all possible, I would also avoid using Office Interop.
