MSIX Packaging Tool- 0x80131500 when building

Recently tested converting TortoiseSVN msi package to MSIX using MSIX Package converter. Everything worked fine during monitoring phase and during build the tool struck up and showed an error code 0x80131500.


When checked for the msix log file it showed error stating duplicate ID's in the Appx manifest file.

[3/7/2019 6:38:14 AM] [Error] ERROR: PRI191: 0x80080204 - Appx manifest not found or is invalid. Please ensure well-formed manifest file is present. Or specify an index name with /in switch.

[3/7/2019 6:38:14 AM] [Error]

[3/7/2019 6:38:14 AM] [Error] error C00CE1A1: App manifest validation error: The app manifest must be valid as per schema: Line 20, Column 2554, Reason: 'f26e2640-0cff-43dc-8325-575a3261d885' is a duplicate key for the unique Identity Constraint '{}Class_Id'.

[3/7/2019 6:38:14 AM] [Error]

Since there was no output generated other than the log file, it was hard to find a solution. So when checked in MSIX Techcommunity it seems it is an issue with MSIX tool build v1.2019.110.0. This issue is resolved in latest insider build v1.2019.304.0.

Thanks to JamesPike & Tim Mangan for confirming this issue and its resolution.

Later have been seeing issues when removing earlier versions of Adobe Acrobat DC and installing newer version in windows 10 1703/1709 which has been explained very well in the below blog by Ryan Ververs-Bijkerk

The solution was to restart the machine and try again earlier. Now this is fixed with the release of new updates for windows 10.

Build your first MSIX Package using DAC

Microsoft is building up a MSIX Packaging Tool which we are expecting to be released pretty soon. Till then how to create a MSIX package? It's very easy. If you have used Desktop App Converter tool to create .appx package earlier then you are ready to create MSIX.

The steps to create MSIX are pretty same like how we create .appx using DAC. You can follow the below link to create your first MSIX package.
