I need help with 1.2

[455trt43trg]

Always when i try to install patch 1.2 i get following error.

I have uninstalled whole game couple of times and downloaded uptade many times.
But it wont help.

Uptade always seems to be looking game files from C:/windows but i have game in D section.

I tried to create folder C:/windows/data/sounds/events.dat but then installer gave me same error again. But it was saying about next file this time.
I have Windows xp.

Any ideas what to do?
