Release 7.3.0.0 for both TMEditX Editor and TMEditX Tools is out. This blog contains the release notes for each.
TMEditX Editor is the licensed and much more capable tool for fixing up MSIX packages, better than PsfTooling since it doesn’t have to depend on the Microsoft MSIX Packaging Tool to create the final package. [Download_page]
The release consists of the following features, changes, and fixes:
Psf V.2026.07.01
Updated version of the PSF. See release notes on PSF changes on the two releases: PSF 2026.05.01 Release – Confessions of a Guru and PSF v2026.07.01 – Confessions of a Guru. Neither contain significant changes.
Code Refactoring.
To improve maintainability, several portions of the code were “refactored”, meaning that code was updated without an intent of changing functionality. This often means combining multiple functions that do the same thing into a single function, or updating logic to be simpler. Ideally, this causes no harms to package updating.
Added ability to import registry files in the C.Registry
You may not add .reg or registry .dat files by right clicking on the virtual registry. This is primarily intended to support the creation of a Modification or Framework package started when using the New Package feature added in the last release. This simplifies the creation of modification packages being created for the purpose of customized configurations, or to add simple plug-ins that do not need an installer.
Add Support for Com5:InProcessServer with Class and ProgId
We finally figured out how to work around documentation issues on this schema extension. This will fix a few long-standing apps with COM issues, for example AutoDesk Design Review works at last.
FIX: AppXManifest Validation Issues introduced in 7.2
In the 7.2 release, a mistake was made that prevented manually edited AppXManifest files from passing internal validation. The issue is fixed in this release.
Change: Allow for installing perpetual product after license expiration.
TMEditX is a perpetual license, but requires paid support/maintenance after the first year. Without support, you are allowed only to install the last release of the software from when you had support. When we changed to the new licensing model in 6.0, we did not consider the scenario where a customer drops support, but later needs to install on a clean VM. In that situation there is no license and you can no longer register using the expired license. Code changes in this release allows the customer to contact us for a perpetual license. This license does not expire, but is node locked to the licensed version.
Change: In 7.0 we introduced a customer requested feature to not increase the minimum OS target when updating the AppXManifest that required that OS version. We recently discovered that this prevented the package from installing in one case (even though the schema was marked ignorable). We will now update the minimum OS target version for this particular case, regardless of the opt-out. The increase is to version 10.0.18362, which is an OS version no longer under Microsoft support so it should not cause customers an issue.
Small changes in VHD/X Conversion
Some small changes made in this conversion code, updating to Microsoft utility updates.

Feature: Multi-Select on MSIX Packages
On the MSIX Packages tab, you may now multiselect a set of packages from the list (Shift click or Ctrl click) and then right click to install or uninstall the group of them.
Change: Progress bar during refersh.
The small progress bars shown when refreshing the package list were changed to a green/red color scheme to make it easier to see when the refresh is still in progress. This matches the changes made in the TMEditX Editor in the prior release.
