I use TMG 9.05 and have recently upgraded to Win 10. Yesterday I encountered the "request for unlock code" phenomenon.
I have consulted Terry's excellent web site and run through the procedure he describes. It did not work.
I have uninstalled and reinstalled TMG and then gone through Terry's procedure again on first invoking of the program - still no success.
The situation that I find myself in is that starting TMG normally gives me the request to unlock, but starting it as an administrator goes straight to the welcome screen, from which I can enter the program as usual. So I can no longer enter the unlock code as an administrator!
Further to the above, I decided to try running the installer as administrator (since other posts indicate that this can sometimes help). However, the most recent installation of TMG will not uninstall. I get a message that "There is a problem with this Windows installer package. A program required for this install to complete could not be run."
I have tried to download another copy of the 9.05 installer in case mine is in some way damaged or incomplete, but the link to the final versions now gives a "404 - file not found" error - what to do now?
