I have sucessfully thinapped a application called Mckesson Star Navigator which is a all purpose medical billing application used by many hospitals. However this app requires mdb files to be downloaded from the server whenever there is a new update. The files gets downloaded to %allusersprofile%\mckesson. Since I don't want to include these files in the package or deal with constantly updating the package I set the isolationmode to Merged for that directory as well as the entire package. In testing this using a cmd prompt entry point I can create directories and files in thtat directory. When I start the app and have the server push the files, I see a zipped copy of the file gets downloaded called adt.uue which should expand to adt.mdb but it doesn't and generates an error instead " unable to create file or something". So the initial file is getting downloaded but it's not extracting properly. Has anybody seen this before or know of a workaround?
