The RAR file included in the installer is asking me for a password which I cannot seem to find. Can someone point me in the right direction for this, please? I can't extract the installer files otherwise. Thanks.

There's no rar file requiring a password.

Installer is divided into two parts, but if you run executable it will automatically use the other one in the installation process (the same goes with installers with more than two files - start setup executable and it will take care of everything). There's no need to extract installer.

Bonus materials are compressed, yes, but they do not require any passwords to extract them.

That's... weird. You could try redownloading the exe (or even both) or moving setup files to other directory and try again, but otherwise I don't think I can help you with this. It may require asking GOG support for help.

By the way, installers are created with innosetup and you can't extract them using regular winrar or winzip programs. You have to use innoextract, but the problem isn't in extracting files but with setup itself, IMHO.


Edit: Another: that's weird. :P

If you downloaded it via Chrome, that's the reason. ;)

When a game consists of more than one file, my pc ask`s me if I want to open them with VLC, so I have to make sure every time that the "save file" option is checked or else the file won`t be downloaded correctly!
Weird? But so it is written....

really? what other browser should I use chrome is clearly the best?

Just for your interest, the KotOR installer actually does have a password.
A while ago GOG created a few new installers with password-protected RAR archives, KotOR being one of the games affected. Forum users complained of course, since it made life more difficult for those of us who like to extract the installers and there is really no good reason for it.
The password is a MD5 hash: 191038cdd4c20f7ea304acad844868a3, generated from the game's ID (1207666283).
innoextract will actually automatically extract the archive by providing the password for you.

If you can't enter the correct password, why not use a method like online website to bypass the RAR password? You can get it here.
Step 1: Go to the website of the online rar converter.
Step 2: After you have the site, browse your password-protected RAR file.
Step 3: Click on the conversion file.
Step 4: Once you provide this command, your file will be converted to zip format and the password will be deleted.
Step 5: Download this zip file, it will have no password.
