App Crash when is Installed Office vb6

Hello to everyone.
I have an application written in vb6.

I use a form to save 25 images. In this form I use GO GO Picture Viewer for resizing them.

Some clients tell me then after they click on Close Form button the application crash without displaying any error. This is very annoying.

This error "magically" disappeared when the user uninstall and after reinstall Office with the official licence.
But I don't know if there is a link between this.

In addition I have done a Debug of the application and the response was here:

STACK_COMMAND: .cxr 18e3e4 ; kb ; ** Pseudo Context ** Pseudo ** Value: 1c ** ; kb

But I don't know where is the problem.

Do some of you have the same problem?
Thanks to everyone
