Here are my specs:
--Running Windows 10 Home 64bit on a Dell Inspiron 5090 desktop PC. Intel Core i7-9700 CUP@ 3.00 GHz [8-Core/8-Thread 12M Cache, 4.7GHz Processor w/ Intel Turbo Boost Technology]. 16 GB memory. NVIDIA GeForce RTX 2060 SUPER 8GB GDDR6 and NVIDIA High Def audio. All completely updated w/ latest drivers and Win 10 updates. Running games at 1920X1080 on standard monitor.
So, will THIS game run on MY PC without a complicated "only PC experts can get it to work"...workaround?
I don't expect any answers on these forums anymore, but I had to get this out there. I'd love to replay this game after so many years. Thanks.

The game runs fine even under Windows 11. The matter is that sadly it has one, for now, unsolvable glitch. Not gamebreaking, but annoying, it damages what I consider an useful QoL feature. The photos you shoot are just black screen. You will need to take visual notes manually

But once you let the game and legacy/compatibility features be properly installed by the GOG install it should run decent and finishable.

Greetings

Thank you so much for your answers.
To others who wish to know: I installed this and downloaded it with GOG. Check my specs (above)> Game began running fine, and continued to play just fine. The only issue is (as noted elsewhere), one can't use the camera as-designed in the game for the original (1996) players of Timelapse.
Happy issues to note:
-Pressing space bar while in the game even brings up the menu, and everything in the menu works perfectly (saving, opening saves, quitting, playing credits, reading journal etc etc...everything except taking photos).
-CTRL-S saves the game. You will be directed (the first time you save) to the game's folder. You can name saves however you want to.
-CTRL-O opens a saved game (once you've saved a game); you simply need to pick the save game you want to load.
-Colors look great within the game (for me, anyway). Beautiful, full-screen as-intended (at least on my 1920x1080 PC monitor). Only the QuickTime videos (for instance, the opening scene w/ narrator which follows the open-logos) look pixellated (because my PC doesn't run on that old color scheme anymore). Game itself looks gorgeous, as it did in 1996. Something else that's great is that when I quit out of the game (CTRL-Q or after selecting QUIT GAME within the (spacebar) menu), my color scheme doesn't change...my new games play just fine.
So: other than taking photos, it all works great (at least on my 4-yo ,Win 10 PC).
-And the BEST thing? If, like me, you backed up your saved games from Timelapse YEARS ago (which I always dragged onto each successive saved games-backup for each new PC I've gotten over the years)? THEY STILL WORK! I dragged 1.TL, 2.TL, all the way through my other 85 or so saves into the new GOG-Timelapse folder, and when I recall each save, they ALL work! SO I can either play again from the beginning, or re-call old saves. Great use of $1.62 (the game's on sale now)!
