Our installers come with a workaround for this, but it doesn't work on some systems.
There are two ways to get around this problem.
a) Install the game into a very simple folder.
The individual folder names cannot be longer than 8 characters. Ideally, it should also be located on drive C:, for instance:
b) Make sure that the \GOG Games\ has been created by you, before installing the game.
In some cases, the operating system can assign weird permissions to a folder that was created by an installer. To get around this, you should:
- rename the \GOG Games\ folder to something else,
- create a \GOG Games\ folder yourself (thus giving it your ownership and access permissions),
- move the contents of the renamed folder to the new \GOG Games\ folder,
- once the renamed folder is empty, you can delete it,
- reinstall Larry 7.
At this point, the game should have the appropriate permissions, despite being installed under a complicated folder path.
