Crashing the App-V 5 Sequencer, Part I of ???

Thought I would pass this on.

Microsoft is aware of it already and confirmed it is an issue. Although it, at first glace, appears that adding a File Type Association while in the sequence editor causes the sequencer to crash, I can confirm that on other apps I can add new file associations just fine.

OS: Windows 7 SP1 x86
App: PaintDotNet 3.5.10
Sequencing Instructions:

  • Custom installation, uncheck Desktop shortcut and Auto Updates.
  • Continue to modify the package in the “Sequence Editor”.
  • Select the “Shortcuts and FTAs” tab.
  • Open the file associations for the application. There will be two FTAs, but I decide I want one for png.
  • Right click add new association. Name it “png” with perceived type “image” (just like the other two).
  • Save the package.
  • See this:
    Sequencer Crash
  • Detail states it was an attempt to dereference a null pointer
  • Workaround is to manually add FTA while in monitoring mode.
  • Appears to be specific to this or only some apps. Other apps I tried this with had no issue.
