**FIXED** GO TO EDIT TO SEE HOW

Same issue with me, no videos.

- Installed to another directory
- Ran as admin
- Used command line fix
- Restarted (sometimes fixed it in the past)
- ddraw fix doesn't work (crashes when attempting to install it)

EDIT: The ddfix linked here doesn't work. This version does work 100% (ddfix 1.5.5)

I don't care if it's an old version or not, I'm not downloading and faffing about with a hex editor to try and get it to work. This works fine.

This worked for me!

Think we found the problem then.

used this ddfix1.5.5 and the videos still didn't work.

This works.
*RUN THE GAME AS ADMINISTRATOR* Were the key words I was missing for awhile.

i tried this and it didn't work

edit: had to run the game as admin to get it to work now the only problem i have is that there is no voiceover on the briefings

Here are some tips that may or may not work.

Firstly the Theif Gold installer defaults to installing Thief Gold in this folder patch.

"C:\Program Files\GOG.com\Thief Gold\"

Theif Gold is as we all know is an old game and dosn't handle dots in foldernames correctly apparently.

So try changeing the install path to this:

"C:\Program Files\GOGcom\Thief Gold\" (notice it dosn't have a dot in GOG.com but just says GOGcom in one line)

Also on Vista and Windows 7 there are some folder restrictions to the Program Files folder, so if you use Vista or Windows 7 I reccomend this installpath instead:

"C:\GOGcom\Thief Gold\"

EDIT: Just tested again and Thief Gold did playback the videos when installed to
"C:\Program Files\GOG.com\Thief Gold\"

But you can still try it out to see if it works /END EDIT

Secondly try and register ir50_32.dll as others have suggested

However if you have Vista and Windows 7 64-Bit you should register dll files like this:

Go to your Windows folder and then to your SysWOW64 folder and find the cmd.exe in there and run it as an administrator

then type:

cd c:\windows\sysWOW64

followed by pressing enter

then type regsvr32 ir50_32.dll and hit enter again

let it do its thing and exit.

The reason for this is when you run the cmd.exe from the SysWOW64 folder you use the 64-bit version of regsvr32 wich lies in the SysWOW64 folder, and not the 32-Bit version from the System32 folder.

And the regsvr32 wich lies in the SysWOW64 folder should register dll files correctly for 64-Bit systems

While the regsvr32 in the System32 folder is used to register dll files in a 32-Bit system.

Sometimes it helps registering a dll file with both versions of regsvr32, first the one in the System32 folder, then the one in SysWOW64 folder on 64-Bit systems.

Lastly try and apply the DDFix if all else fails.

Hope this info helps

YEA!!! after the
- ir50_32.dll thing in cmd as administrator
- ddfix 1.5.5
- playing game as administrator

the videos finally works in windows 7 64 bit! Thanks a LOT!

Ahh good to hear..

maybe try clicking on the sticky topic? it fixes the movie problem permanently, among others.
