What if I have RTW gold?

[spartancrotty]

Will it still work?

The version doesn't matter as long as:

The game is patched up to BI 1.6 (most Gold versions are, but not all, so do check)
The installation is correct (just follow the instructions)

If the game is BI 1.6 and the instructions followed, then yes, it will work just fine.

I have RTW Gold as well, and BI 1.6, yet every time I start the installation and get to the 1st next after you select your language, it says "Rome - Total War - Gold Edition is installed on this machine, this patch is not compatible."

If you have BI 1.6, why try to install a patch? Just install the mod.
