For some reason, I can no longer successfully open Windows compiled help files (i.e. those with the .chm suffix).
This just happened and I don't know why.
The program associated with *.chm files is the C:\Windows\hh.exe (that's the correct program!), but when I attempt to open such a file (lot's of my Photoshop ebooks are *.chm files, for instance), I get an error message like the following:
"cannot open the file: mk:@MSITStore:c:\(path to the help file)"
If MSITStore is a program, it isn't one that I have on my computer -- I've searched.
Any help would be appreciated,
