XnViewMP 0.75 : file association

[arch21]

this button doesn't work. when I investigate the registries, entries with prefix XnViewMP(XnViewMP.bmp, XnViewMP.png) getting changed from xnviewmp.exe to xnview.exe after I click the button. Also, I can find it on "Set your default programs" after I click that

you means that you had before association with XnViewMP 0.72??

I'm sorry if I couldn't explain it clearly. What I mean is the button on menu Tools->Settings->Integration->Run the File association(s) tool....
If I remember correctly when I was using v0.72 back then, it open file association setting. In this v0.75, after finish installation, I can set it via Control panel->"Default Programs"->"Set your default programs", I still can see "XnViewMP for Windows". Once I click "Run the File association(s) tool..." button, it doesn't appear.

Not sure if this helps, but you can go into Xnviewmp install folder and double click the "Associate files with XnViewMP.exe" file and it will open the dialog. this worked for me.
