1. I compiled my dlls using VS 2008 and changed the file versions to the new minor upgrade version (as I do always). 2. I built a minor upgrade successfully using Installshield 2009. 3. I upgraded my station to the new minor upgrade successfully. 4. I did file comparison between the output dlls from the compilation of step 1 (that the installshield took and make a package from) and the dlls that were installed at my station after the succeeded upgrade. (using windows tool: fc /b dll_after_compilation dll_after_upgrade). 5. they are suppose to be the same. They have the same file version but the result of the binary comparison is that they differ:
fc /b "c:\After compilation\V.dll" "c:\After upgrade\V.dll"
Comparing files c:\After compilation\V.dll and c:\After upgrade\V.dll 000015AA: 15 FA 000015AB: 00 48
the dlls are not com dlls.
Does any one knows why is the difference between the both. it should be the same dll ??
Sorry if this is an obvious response but it sounds like you are saying you had an installer with dll lets call it "A". Then you recompiled the dll with a new version number and built a new installer with it and after you installed you did a comparison expecting the dll to be exactly the same sans version number; is that correct?
If that is the case it should not be a surprise a binary comparison shows a difference between the two dlls.
*edit
Apologies in advance if I am misunderstanding your question
