Trouble installing TSL in Windows 7

[emeralddarkness]

First off, I do know about the fix shown here. It worked beautifully for KotOR, everything runs fine, all is well. HOWEVER, when I try installing TSL, things work until I hit disk 4. Once I try finishing the installation with disk 4, however, the following happens.

 

First I get this message:

 

[Feature transfer error

 

Feature: Star Wards Knights of the Old Republic II: The Sith Lords_Files

Component: DefaultComponent

File: C:\Program Files\LucasArts\SWKotOR2\StreamVoice\262\sister\262s34d6.rra

Error: Access is denied.

 

[Ok] [Cancel]]

 

I've been hitting [Ok] and a few seconds later everything shuts down and I get the following message:

 

[WerFault.exe - Wrong Volume

 

The wrong volume is in the drive. Please insert volume KOTOR2_1 into drive D:.

 

[Cancel] [Try Again] [Continue]]

 

Um.

 

... help?

 

Sorry if this should be somewhere else, it didn't seem to fit any of the categories in the stickies....

You most likely have a dirty or damaged disk, or a bad drive. Try installing the game on another machine. If it works, you've got a bad drive. If you get the same or similar error, you've got a bad disk.
