Cant apply 2.05.13 to retail GOTY (im using the GOTY patch)

[mr_nicken]

Bought my MoW GOTY from Greenmangamming digital download.
Version 2.00.11 - Retail

Trying to apply patch 2.05.13 so i can join the rest but no luck.

"
The setup has detected that no version of Men of War. Assault Squad -
Game of the year is installed.

The update requires a previous version of the game to be installed.
Set up cannot continue.
"


So i tried
1: Register with Steam ( got no key for that)
2:Use Uniexctract and patch my self (wont work )
3:Use NON GOTY patch (patch work but need to enter key again)

Please advise
