Resolution: After a R02 upgrade the citrix specific version of the DLL files are updated. If some of these are copied to other locations listed in the windows %path% variable, naturally these are not updated by the R02 Script. These files might get utilised instead as windows uses the path variable in the order specified (%systemroot%system32) Simply delete the auxillary DLL’s – or upgrade the same DLL in the auxillary locations. In this instance it was c:program filescitrixsystem32ctxprn.dll version 4.5.3276.1 vs c:windowssystem32ctxprn.dll version 4.5.3750.1
