Bumping this and adding some further information from another thread on the topic where others are having this difficulty (for the game Wizardry 8 anyways, I am not collating all the potential issues):

Right, let me try this again.
I am !!NOT!! talking about Galaxy or the Game Version (which is 1.2.4 in both cases).
So, OFFLINE installer setup_wizardry8_2.0.0.6.exe, which is no longer available under the download offline installers on the website, but which I have backed up works flawlessly. It also contains prebuilt characters and a Saves folder already in place. It also plays the movies fine and launches correctly.
setup_wizardry_8_2001_12_23_(22306).exe which is the one now available on the website for download has the following issues:
It screetches at each movie start.
It opens with resolution 1024*, whereas the previous one opened full screen.
It does not play the start movie, nor does it start the game, just crashes at that point.
The instal does not contain a Saves folder, has no premade characters.
I will add this information to the main thread, and wishlist and other links here:
https://www.gog.com/forum/general/provide_a_full_and_complete_changelogged_download_system I can repeat the above as many times as needed, all exactly the same issues. Here is a directory listing of the two versions, which quite clearly show the second one is missing the Saves folder completely, and has a different size. As the game version has not changed, GOG have changed something between the two versions and removed content. I have asked GOG about this, they reply with the standard "use galaxy to be able to roll back":
