Our compatibility settings support wildcards, so you could use this line to prevent DisplayFusion from hooking any files in that temp path:

Code
Copy
Select All

C:\Users\Chris\AppData\Local\Temp\*


Thanks! ]]> RE: Display Fusion locking files preventing some apps updating https://www.displayfusion.com/Discussions/View/display-fusion-locking-files-preventing-some-apps-updating/?ID=d2d3d1d1-1973-42cd-9d1e-ca942be88798#3 Wed, 10 Aug 2022 13:32:34 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/display-fusion-locking-files-preventing-some-apps-updating/?ID=d2d3d1d1-1973-42cd-9d1e-ca942be88798#3 DisplayFusion

Hi Chris,

DisplayFusion is likely trying to hook into the process it's trying to update. You can add it into the Compatibility tab in DisplayFusion, and turn on "Disable Application Hooks (this application)", and it should fix that up.

Thanks!


I use an app which automatically updates a wide range of installed software.

When it runs, it downloads to a temp file and spawns a child process which is the updater.

eg.
C:\Users\Chris\AppData\Local\Temp\eabb0cd9-18af-11ed-8cda-bce256a95a14\target.exe


This is a random path, and only exists for less than a minute while the updater runs.

It looks like the compatibility feature doesnt extend to child processes executed by the parent as a still get the lock. ]]> RE: Display Fusion locking files preventing some apps updating https://www.displayfusion.com/Discussions/View/display-fusion-locking-files-preventing-some-apps-updating/?ID=d2d3d1d1-1973-42cd-9d1e-ca942be88798#2 Mon, 08 Aug 2022 15:56:32 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/display-fusion-locking-files-preventing-some-apps-updating/?ID=d2d3d1d1-1973-42cd-9d1e-ca942be88798#2 DisplayFusion Hi Chris,

Whenever I install an update (which is weekly), the k-lite installer will say "Display Fusion process is locking files, preventing update".

I'm required to kill the DF process, click OK on the installer, and re-run DF after the update.

Is it possible that this can be investigated to see if the locking is required, or if the files can be opened in a more permissive way? ]]>
