For some unknown reason, my image file associations in Windows Explorer keep getting undone, such that they show up in Explorer without an associated application (or occasionally with a wrong association).
For example, when I examine the properties of any .jpg file, the "Open With:" property says "Unknown application".
My default image file viewer application is ACDSee Ultimate 8, and the registry key for .jpg files looks like this:
However, as I say, that never seems to get propagated from the registry such that Explorer will correctly open ACDSee when I double-click an image file (ALL image files are the same, not just .jpg). The question is: WHY?
I've tried creating a .REG file that contains all the correct registry settings, but when I merge it, nothing actually changes!
And naturally I've tried running the following command to force the registry to be freshly loaded:
C:\Windows\System32\rundll32.exe USER32.DLL,UpdatePerUserSystemParameters ,1 ,True
But nothing seems to work!
I trust you've seen that I'm a very knowledgeable user who is not struggling with primitive questions, but I'm at a loss. What, exactly, am I doing wrong? What do I have to do to FORCE a change to all the file associations such that they'll open in ACDSee when I double-click them?
