How to install Dragon Age 2 patch 1.02?

I've successfully installed, and currently playing the 1.00 version. But when I'm about to install the 1.02 patch, this message "Dragon Age II was not found. Please reinstall the game and try again." kept on popped out. Anyone knows how to resolve this?How to install Dragon Age 2 patch 1.02?
Have you cracked the game? Because maybe it doesn't recognize the exe. Or do you have it placed in a custom folder not in your Program Files folder? It is possible it doesn't recognize the folder my Dragon Age 2 folder lies in C:\Program Files (x86)\Dragon Age 2
Hope this helps

Well the problem probally is that the installer doesn't recognize the crack you have to reinstall the game you don't have to lose your savegames just go to Documents then Bioware and copy the Dragon Age 2 folder and paste it on a save spot so you can replace it with the new folder. Maybe the unistall already asks if you don't want to lose your savegames so than that what I said before isn't needed. Ow and don't replace the the exe with the crack before you updated the game and you might also need to download a new crack if you update it. And if it still doesn't work you might put your update installer in the D: drive sometimes that is the problem that it will only find in your C: drive the game.

Hope this helps

ow and if you downloaded the game free maybe consider buying it because Bioware is a good game publisher and deserves to make their money from computer games but if you don't think this game doesn't deserves it you don't.
