Barbara,
Thanks for the suggestions. The EXE is calling the prgs files as just another line of code. They are all in the path of the exe. I just did not anticipate having this type of problem, but then I have never done anything of this nature before. If I put these prg files into the project and exlude them the error handling screen is found, but the class library is still not found. I could rewrite the error handling screen to just use generic classes. I may try the error.exe first. Again, Thanks...
