Typically in the installation directory but... Hmm, so if the file cannot be created in the installation directory during activation, it is created in

C:\Users\[UserName]\AppData\Local\PrestoSoft\ExamDiff Pro

Maybe when EDP setup could not find the license file, it is located in that alternative folder. Still, it doesn't explain why it cannot file previous installations.

Please check the Registry keys mentioned above: if there is a bug, it would help us fix it. On the other hand, this should not prevent you from using version 16: after all, you can always uninstall previous versions using Apps and Features. Still, we would definitely like to get to the bottom of the issue.

I have an entry in HKLM but not in HKCU.

More precisely I only have an entry in HKLM under "Software\Microsoft\Windows\CurrentVersion\Uninstall".

Please try what is described in viewtopic.php?p=9173#p9173

Please try the latest build (16.0.0.3) - we made some installer fixes there.

Just wanted to confirm ver 16.0.0.3 did finally have the check box and successfully uninstalled ver 15, found my license and installed ver 16.

Thanks for figuring this out
Steve

Thanks for confirming.

"password.bin" in the old V15 install directory.

Move that to the V16 install directory did the trick for me.

Hmm, so during the installation, did you see a screen confirming that you still had a valid license? If so, password.bin file should have been copied to the new installation folder by the setup.

Hi psguru,

Yes, I did see a screen confirming a valid licence.

However, the password.bin file was not transferred to the V16 directory. Had to do it manually.

Thanks. Hmm, it should've been. We are going to add more logging to the installer, to see why the file was not copied.

FYI, the installer creates a setup log file in your %temp% folder, like Setup Log [timestamp] [number].txt. If you find it, please attach here.

Hi psguru,

Logfile attached from an X64 install.

Cheers,
Leslie

Thanks! The log shows that the previous password file (ver. 15) was found but, according to you, was not copied to the new folder. As I said earlier, we added some additional logging to the upcoming build; perhaps that will clarify the reason in future.

By mistake I went with the default and installed the latest version in a different directory from my standard.
Result: unregistered.
I repeated the procedure with "log=setup.txt" and, voilà, everything was fine and the licence was found...
Murpy strikes again.
