This could possibly be the problem, I'll have to do a check with the user as soon as possible.

One thing I noticed was that on my PC, the file does work fine. However, I am using Office 2003 and the MSCOMCTL.OCX file is not up-to-date.

My colleague beside me can also open the file, and he is using Office 2010. His MSCOMCTL.OCX is up-to-date.

The user who has been having the problem, has Office 2010 and his MSCOMCTL.OCX file isn't up-to-date, I'll see if I can update this. So I'm wondering if it is to do with the MSCOMCTL.OCX file and Office 2010?



I will let you know the outcome.

As you can see by the path the MSCOMCTL.OCX comes with the OS and hasn't got anything to do with MS Office - it only can be used by the Office program.
Just for you to know: There was a problem with the update of this file, so you might experience difficulties to install a newer version of the file. Therefore I suggested, to contact the external company first. The developer should know what's required to run his "program" and if MSCOMCTL.OCX is really the cause of the error.

... yes I would apreciate to know any solutions you find, or even if not ...

No luck updating that file

Going to contact the sender of the file, it's strange how only two people (so far) have the issue opening the file. While, myself and a colleague can open it completely fine!
