BUG: Can't set file type associations in XnView...

We can't set file type associations in XnView, the options are grayed out. It works fine on Win7 but not on Win11. Normally, I want to click the "the most used" button option. Please fix.

but it is a big hassle to have to manually set associations in windows settings. can you fix it to make the xnview association options work in win11, to be more convenient? normally, i want to simply click the "the most used" button option.

Unfortunately it doesn't work. I tested. :(
The answer to why is here: https://www.dedoimedo.com/computers/win ... assoc.html

"From Windows 10 20H2, none of these solutions really work for an existing user. If you want to make changes, you can, except, the system will totally ignore them. Moreover, Windows now also assigns a hash to any program & file association, and this hash is used to verify that the change is legit, i.e., done by the user. So you can't really go about manually mucking through the registry, because Windows will ignore your manual changes, as they won't match the hash. How is the hash computed, beats me."

its possible to set assosiations via SetUserFTA (guy reverse engineered hash generation), unfortunately no source code available

example for xnViewMP:
SetUserFTA.exe xnAssociations.txt

xnAssociations.txt

Code: Select all

.ico, XnViewMP.ico
.icns, XnViewMP.icns
.jpg, XnViewMP.jpg
.jif, XnViewMP.jif
.jpeg, XnViewMP.jpeg
.bmp, XnViewMP.bmp

.ppm, XnViewMP.ppm
.ras, XnViewMP.ras
.rle, XnViewMP.rle
.xbm, XnViewMP.xbm
.xpm, XnViewMP.xpm
ps. as far as I remember there is no XnViewMP.jfif hive for some reason, so you need to create it and than add .jfif, XnViewMP.jfif to the config above

I had issues launching XnView MP from Windows Explorer with any type of image file, SetUserFTA saved the day using your example. Thank you :)
(I'm going to put that into a BAT file so next time I need that trick I won't need to search in the forum again xD )

Note: I'm using Windows 10 21H2 and using the settings didn't work; this trick is easier anyway
