I found a lab case for the 7.01 patch bundle that describes the problem this way:
EXPECTED BEHAVIOR:
- remove_patch script should remove all the files which have been copied to the clients with the patch bundle installation.
- Installation of a the patch bundle should work again after it had been removed with the script
What is not clear to me is if this script is part of the patch bundle installation package
fails because previous 7.01 build was different version that the one beeing pushed and since internal build number of 7.01 is actually the same, windows installer detects it as unknown upgrade version.
"This is only the case in testing environment and will never happen in production environment."
Well, this is obviously wrong
I also found 3 more cases where this occurred when installing DP 8 client components. The cause for all 3 was different build versions for the same patch bundle
One recommended (by the error message) is to use Add/Remove Programs. I am not sure that is a good idea, I don't know if the patches in the patch bundloe totaly replace ALL of the executables for each component
There is also a script, the description is at the bottom of the Installation Instructions on the patch description, but, I don't think that either of these apporaches is a good one. You should be able to just do a push from the Client context
When did you download the 7.03 patch bundle? They may have fixed teh Build version problem since the download
