Maybe because you have a registry error of the game in Inno Setup.

Made 3 images, installed fine from them. Wouldn't uninstall, resorted to simply deleting the game directory.
Trying to re-install from burned discs now to check they're ok, only options I get are play or uninstall even though there's no game files or even folder anymore. Looking in registry I cant see any references to the game.
Suggestions very welcome.

EDIT - Nvm, found a registry entry I missed (tyvm win7 lol).

Installs perfectly here on win7 64. Thx for the conversion.

,,noob,,before you convert must delete the old uninstall files,3 or 4 files!!Now go in Start\Run\Regedit\HKEY_LOCAL_MACHINE\SOFTWARE\CD Project RED and delete CD Project RED,go in Start\Run\Regedit\HKEY_LOCAL_MACHINE\SOFTWARE\GOG and delete GOG go in Start\Run\Regedit\HKEY_LOCAL_USER\SOFTWARE\CD Project RED and delete CD Project RED!!Now reinstall original game ,move elsewhere the old uninstall files,and convert game!!After conversion has finished move back old uninstall files and uninstall original game!!Only now you can install what you resulting from the conversion!!

How much time it takes to install with this conversion?
I'm trying to install here and its Extracting pack0.dzip from disk1 long time...

I figured what happened, the screen with the Please insert next disk is hidden I dont know how, betwen the background image and the progress bar screen, I can see it pressing Alt+tab, but its not selectable, very strange thing, I cant acess it and cannot continue with instalation.

Hi mate, just need to confirm, so we can install and uninstall the game without problem in v1.1 ?

it works fine with updates.

If I simply delete the extra language files rather than replacing them with dummy files,Will it show any error while playing the game ?

is possible to remove multiplayer + foreign languages? and what size is ?

hello

Is it possible to create an autorun.exe and setup.exe?

Lol, I forgot I even made this, it made me laugh when I saw I was the OP.

I don't remember how this was made, but I will not make any modifications or another conversion for it.
