yamo: I did not dl the other 5 parts...i just "opened" the first one. Do i have to create a directory to store all 6 parts in and then run the first part? What should that file be named?
When you select "open" your browser saves that SINGLE file to a temporary folder and then opens it (as if you had double clicked on it)
You don't have to be a "tech wizard" to figure out that if something says "part 1 out of 5" you need to get ALL FIVE PARTS for it to work.
Here is what you should have done (don't do it now, see below):
1. Make a directory
2. Download each part to that directory. Use the default names
3. Run the installer.
Also, why are you choosing to use advanced user options like manual download when you could just use the simple and straightforward GOG downloader which does everything for you?
http://www.gog.com/downloader Here is what you should do:
1. Install the gog downloader, once, use the "open" command.
2. Close your browser, then open it again.
After you do that you can from now on download any game you want using the gog downloader. (no need to repeat the above procedure)
