A FIX for invalid serial number after updating WinDVD!

[Ludovic]

Symptoms -

You reinstall WinDVD Pro 11 on windows 10 (or 8 etc)
You install the latest update to fix issues with windows 10, only for it to complain about an invalid serial number and exit (after uninstalling your copy of WinDVD Pro 11)

SOLUTION -

Don't try and install the non PRO version of the update WinDVD_11_SP5.exe like I just did...
Instead install the WinDVD_11_Pro_SP5.exe version

(and I'm guessing vice-versa)

Sadly, no. I have the pro (trial) version and it won't work on Windows 10, so I tried the PRO SP 5 and I get the "Invalid serial number" and uninstall...
