Thank you for the tip about deleting the minor upgrades. I haven't tried that and it seems possible but it is concerning about what it means for future builds. Yes, we will only be issuing major upgrades in the future but will there be any downsides to removing these minor upgrades when we generate a new build? You don't get any errors when you build just the ISM file. How can that be? The project has tons of references to other merge modules that I did not provide. Speaking of builds: does it matter which way the project is built? There are at least 3 ways that I see it can be built: - The 'Build' button in the ribbon bar right at the top of IS2023. - Choose Releases > Choose the Major Product 10.24.1 > Choose the Major Release 10.24.1, right click and choose 'Build' - Build from the command line with: iscmdbld -n -p Exclient.ism -r "Major Release 10.24.1" -b <build location> -c COMP -o <MergeModuleLocations> -e y ...

Thank you for the quick response. I will be opening a case but my account doesn't have privileges to do so. I emailed support@flexera.com to upgrade my account to be able to create a case.  In the mean time...   I made no changes to the ISM project. When I first got the error I was using IS2013. Then I upgraded to IS2023 and loaded the ISM - which converted it to IS2023 format then tried to build and got the same error.   I've attached the requested files. Note: there are 3 other errors in the LOG that only showed up when compiling with IS2023. I imagine those will be resolved easily enough.   I looked at that link for error 6423 and it doesn't seem to apply or make sense in our situation. Yes, the errors indicate there are minor upgrades in the existing project. However, I created a brand new major upgrade (10.24.1) that I want to build. It doesn't make sense to delete those old minors and change to a major upgrade.  Is this scenario allowed? Can I create a major upgrade after previously shipping minor upgrades? ... View more

FYI: I'm the original person who opened this case. My coworker created the case for me. FYI: And there was a suggestion to upgrade from IS2013 to IS2023. I have done that and I get the same error. ... View more
