The system requirements posted elsewhere say Win 7, for whatever that's worth.

Oh, I wasn't expecting a quick response! Thank you! While I was gone, I spotted the actual dev in another forum and I asked him the same question directly. I was about to come back here to delete my post, but you had already answered my question! xD

I appreciate your reply. :) If the actual dev answers my question, I will let everyone here know too.

Update: The dev confirms that dotAGE should work fine in W7. :)

Sniper Ghost Warrior Contracts 2 Complete Edition is OK under Seven.

"Lakeburg Legacies" is OK with seven.

Tiny Witch runs fine on Windows 7.

Time to improve this thread a bit. Some major contributions have been self-deleted, some links dead, and the rest are half-sprawled across multiple pages. So here's a new spreadsheet that combines all contributions from this thread into one, alphabetically:-

https://docs.google.com/spreadsheets/d/1SQRBTM4zbzl0Zf1_Tpo2dTd1zlQzL3FAOiINUV_8ksY

I'll edit my post #5 to perma-link to it so it's almost at the top of page 1. I use Google Sheets for several reasons 1. Collaboration, 2. You can download / print a copy for offline usage, 3. It's not at the mercy of GOG threads being closed / archived or limited by forum post character limits. I'll try and keep it updated but it might be monthly rather than weekly. Since the main problem with these kinds of community lists is that they tend to "fizzle" if all the workload is dumped on just one person, if any W7 using trustworthy (ie non-spammer) regular here wants to be added as a co-author (Google / Gmail account required just to login to Google Sheets, but it's never shared or publicly visible), let me know and I'll happily let you edit the list directly.

Also, 4 games tested:-

+ Gylt works under W7 but requires the -dx11 switch. Version tested : 1.1.1.5
+ The Spirit And The Mouse works under W7. Version tested : 1.32d3

- The Invincible does not work under W7.
- Lempo does not work under W7.

Pandaty works fine under Windows 7.
Can you explain what I have to do? I tried to run this games some weeks ago and it didn't run. I have no idea what the -dx11 switch is.

The game defaults to using DirectX 12 (which W7 lacks). If you go into the game folder and create a shortcut link to the .exe then edit it as follows:-

"C:\GOG Games\GYLT\Gylt\Binaries\Win64\Gylt-Win64-Shipping.exe" -dx11

Then use that link (not a Galaxy supplied one or the .exe directly), does it run then? It's basically the same fix as Myst (2021).

On the desktop shortcut for the game (it must be on a shortcut, not the native .exe), right click and choose properties. On the "target" field ("destino" in my print) just add the " -dx11" parameter after the path it's already there, note the space.

Ninja'd :)

Thank you. That's much easier than I thought. Will try it and look forward to finally play that game. :)

Despite the DX12 needed "Spacebase Startopia", works fine on Win7.

And why not? According to GOG, Lempo does need only DirectX 11?!

Sometimes it's not DirectX version that breaks it, but that the game is compiled to make a Kernel call that's only in W10-11, and throws up a "Kernel error" upon startup.

What a pity! Thank you for the answer, Sir. :-)
