Thanks Mark,
As I stated, ALL class libraries are included in the project, so I don't see why would be the path to the class lib needed.
The directory in which the class libs reside is not even accessible to users.
I don't know if it was clear in the original post, but this error happens only from time to time. 99% of the time everything is fine. It is not one particular EXE, we have over 30 different applications, and it happened in more than one or two cases.
