Has anybody an idea what can cause an Excel customization built on the basis
of MS Net framework to load or not?
I have the problem that the customization used company-wide (without
problems) is sometimes loaded and sometimes not with my PC. The PC was
exchanged, it was re-imaged and several further attempts were made to solve
the problem, including registry cleaning, several de-installations and
re-installations of the customization etc.
The reason for the instable function could not be found up to now.

Thanks for your advice.
