Some epic patching problems

[Kallum]

Spent the last hour googling on how to install the 1.41 patch, I know it seems silly but everytime I start to install, it says "Cannot find Battlefield 2 Folder" and then shuts down, my BF2 Game is on my D Drive but the patch does not give me an option to choose this, I had to resort to Regediting which I found whilst searching but they either came up as Vista or the XP Regedit comes up as EA Games on other peoples PC but DICE on mine, so I cant follow that.

Help would honestly be appreciated
