petritisHexagon asked a question.
I am trying to make a second patch. (I am using InstallShield 2016)
I have the original installer, and a first patch in a couple directories.
My .ism file in InstallShield has those 2 installers referenced in "Media -> Patch Design", then "Patch Design -> PatchConfiguration -> Latest -> Previous Setups" and the correct paths to their .msi files are shown.
When I try to make a new patch with:
"C:\Program Files (x86)\InstallShield\2016\System\IsCmdBld.exe" -x -p MyProduct.ism -patch_config "PatchConfiguration"
It fails with:
ISDEV : error Val0003: The package code for the latest setup does not differ from that of the previous version. In order to perform an upgrade the package code MUST change. c:\patchconstruction\server\16.7.0.1\admin\MyProduct.msi
In the log file it makes I see this error:
ERROR: TargetImages.Target = 'PrevFull2': PackageCode {492FED04-153A-472C-8D82-CC061ADA3C45} is not unique.
I cannot figure out where that PackageCode is coming from.
I looked in my new .ism and the 2 older ones, they don't contain that GUID. I opened the .msi files associated with them in InstallShield and looked at the "Installation -> General Information" setting for "Package Code" and could not find that value.
I tried Orca to see if I could find it, but I couldn't find PackageCode in it.
I would like to fix the problem, I suspect that if I can figure out where that "not unique" PackageCode is, that I can then figure out how to make it unique.
So, any ideas about how I can find that PackageCode?
Or even better, how can I fix the problem where it will not build a new patch.
The "Package Code" is stored in the "Summary Information" Stream and you can see it in InstallShield here:
In Orca you can verify the Package Code here:
To generate a new package code every time you build a msi you can activate the following option in InstallShield:
