When I click on the manual link in the FSDT Installer nothing happens. What is worse, I can no longer open any PDF files. I have to sign out then back in before I can start opening PDF files.
That's most likely because, the first time your reader didn't start for some reason (or maybe it was just starting but you clicked again too quickly), so you clicked the button again, and made the 2nd copy locking the 1st one that might still be in the process of starting, requiring a new login. But you would have achieved the same results if you just terminated the first instance of the reader.
Nothing that has anything to do with our installer, which doesn't do anything other than ask windows to start the file with whatever reader you have set by default to open .PDF and doesn't have any knowledge of it, or even if you have one.
What is the path that the FSDT installer looks for the GSX manual when I click on the "Manual" button.. ?
