I'm having problems with hyperlinks in excel. I have a .ff extension that is a tiff file. I've associated the extension with msPaint in windows, and it opens in paint when I double click it. But when using a hyperlink in excel, I just get a popup saying that no program is registered to open this file.
i've researched and found that the link below resolved this issue for many, but when I run that command against mspaint.exe (or any program for that matter) all I get is a strange message. For mspaint it said: "c:\unregserver.bmp not found"
