Release Notes 


Release  December 9, 2019

Feature/Maintenance Release

Feature:   Desktop.ini Detection/Repair. Recent versions of the App-V in-box clients appear to have issues with packages that include the file "Desktop.ini".  The particular case where this was found was in the user's video capture folder, but other locations may produce the same package launch failure. Desktop.ini is not a file that needs to be in the package. You can add individual entries in your exclusion list in your sequencer template files, but the exclusion lists don't support wildcarding the folder. TMEdit package analyzer will locate any desktop.ini files in your package and offer to clean them out for you. This fix is available in both the GUI and AutoUpdatePackage programs.

Feature:   MSIX Analysis for 1909. Now that Windows 10 version 1909 is available and we are testing with it, both with App-V and MSIX, The MSIX compatibility scanning has now been updated for what we know about 1909.  I will probably update this againin the new year when we have completed the MSIX Report card and we have more experience and details.

Release  July 10, 2019

Feature/Maintenance Release

Feature:   Short Names Recent versions of the App-V Sequencer may produce bad 'Short Name' references in the FileSystemMetadata.xml file in the package. These short-name references may have one or more folders with names that are not 8.3 compliant. These issues have been seen in the 1809 and 1903 sequencers, and are likely in 1909 as well.  TMEdit will detect these issues and can fix them. In addition to changing the Short Names to a 8.3 compliant syntax by using a unique ~T technique, it will also search and replace registry strings for file references that use the mangled short-name reference and update those as well.  This fix is available in both the GUI and AutoUpdatePackage programs. 


Release  July 10, 2019

Feature/Maintenance Release

Feature:   AutoUpdatePackage improvements.Version 1.8 has added several of the fixups that were added to the TMEdit user interface in recent releases. You may now edit the Fixups.xml file to request various file and registry cleanup operations pregiously only available in the TMEdit GUI. 

Fix:    DotNetCompileFix. If you requested the automated fixup to compile .Net components into a package that had no compiled .NET components previously, the package worked fine on the client but could not be imported into the Sequencer due to missing ShortName information for the folders. This is now resolved.


Release  May 14, 2019

Feature/Maintenance Release

Feature:   Analysis/Fixup improvements.Version 1.7 has added two new categories of generalized package cleanups, one for files and another for the registry. Especially when sequencing on Windows 10, the standard sequencer exclusion lists are very insufficient if you want a clean package.  The tool now has a much expanded exclusion list and analysis and fixups that will clean your package of many well-known locations that should never be in your package. The lists are also customizable. Currently, in the Tool Config tab you can review the lists and disable items if you don't want them scanned for. If you wish to append to the lists, please use Regedit against the HKCU\Software\TMurgent\TMEdit items. 

Feature:  MSIX Analysis has been updated for the details related to the Windows 1903 release.

Feature:  Savings on Save When you save the package, information comparing the original and saved files are shown, allowing you to easily see how much space has been saved. Note: If you compile a lot of uncompiled DotNet components, your package can still grow!  

Fix:    Analysis/Improvements A number of small improvements were made to the display on this tab to resolve inconsistencies. 

Fix:    Analysis/Improvements When deleting a file or registry item via the fixups buttons, if the parent folders/keys become empty these will also be removed.. The resulting FileSystemsMetadata file should now be more internally consistent as well. 


Release  April 27, 2019

Feature/Maintenance Release

Feature: Fix:    AutoUpdatePackage improvements.Version 1.6 has added a new option to update the package without specifying any fixes. This can be used simply to improve package compression or to rename (branch) a package.  See the online documentation for details. Also fixed an issue in prior releases where this utility was not updated in the package, leading to a dll mismatch.


Release  April 20 2019

Maintenance Release

Fix: Issue with AppxManifest for URLProtocolHandler with Shell commands not opening in ACE.


Release  March 7, 2019

Feature/Maintenance Release

Feature: Save as Branch Package capability added to the product.  When saving, if you want to branch the package rather than saving as a new version, you uncheck the Save as New Version checkbox and check the Save as Branch checkbox instead.  You'll be prompted for a new package name when you save the package. You'll get a new Package Name, new PackageID and VersionID guids, and the version string will be reset to  If the Description field is unused, we'll add a note about the package you branched from too. 

Fix: Fix issue in situation where user removes a file on the virtual files tab and then adds a file using the same name.

Feature: Added a right-click menu on files on the virtual files tab for Replace. Even though the issue above is fixed, it makes sense to support the scenario this way as well.

Feature: Return of the display of Last Operation on the virtual files and virtual registry tabs. As you attempt to make file and registry changes, the result of the operation is once again displayed at the bottom of the window. This was removed when error reporting was added to the Windows Event Logs, but restoring this display for operations gives readily available feedback.
