MECM MSIX Application Creation Error
Apologies if this needs to go into the MECM forum.
I receive the following error message when trying to import an MSIX into MECM: 'Error: Part URI is not valid per rules defined in the Open Packaging Conventions specification'. The MSIX is for Adobe InDesign 2026. I have successfully created MSIX packages for other Adobe Creative Suite products and imported them into MECM. I have been through the manifest for the InDesign MSIX I created, the file system, the metadata (such as package name) and can see nothing that would trip it up. I have also looked for any path lengths over 255 and found none. The only thing I found which I think may be a problem is in the content_types.xml - a tilda in the application extension entry:
<Default Extension="xml~" ContentType="application/octet-stream" />
As usual, there is not much online. I have skimmed through the OPC specification, but can see nothing about limitations. Have anyone else come across this problem?

Larry,
This sounds unusual.
Microsoft doesn't seem to be reacting to posts here much right now, so if you want to reach out to me offline I can provide another set of eyes. mailto:tmangan@tmurgent.com
