I don't have any compatibilities set on my POP3D.exe and I just launched it on an updated Windows 10 64-bit with no problems.

I assume you have the unprotected EXE I mentioned above, since you are able to launch the game.
Try removing the intro video. In the movies folder, rename the Broder.mov to something else, create an empty TXT file, and rename THAT Broder.mov

The game should skip immediately to the main menu.

Can someone help me out?

I installed this game (english version, first download link) with help of tthat unofficial "popuw" site on my Windows 10 x64 machine, QuickTIme 4 was installed as well and this is my experience so far:

1. At first try, the game will open, display the Red Orb intro video and after that crash to desktop
2. Later on I managed to go to he menus with the unprotected exe I think but this time it crashed during the loading screen :/ man......
3. Now I applied some fixes from that site and this time I managed to actually load the game and play it mostly perfect, mostly perfect because I experienced some strange "lag" if I turn around to specific direction but after testing the game and playing it for a while, I minimized the game and open it again later and now the strange lag was suddenly gone completely (I didnt do anything besides minimizing it). Now the game worked 100% perfect on my Windows 10 x64 machine and one more important thing, I never used any 3D wrappers or whatever they are called (ddraw.dll or dgVoodo), none so far. Game savin also worked fine.....

4. Here is the part where the problem starts, one day later I tried to install the german version and I was not succesful, I even broke the game completely, I cant even open the english version anymore. Nothing happens if I open the pop3d.exe (no error message, the RedOrb intro video never starts etc..... I reinstalled the game several times without any success.

So, basically I actually installed and played this game 100% perfectly before I screwed something up, now I cant manage to even OPEN it again. My goal is to find the solution to install both the English and German versions and to play them correctly on our WIn 10 x64 machines (same solution may be applied for Win 7 and 8 as well).

I can't guarantee at all that this works, but I had a problem that seemed kinda familiar:

I mistakenly applied some 1.01 patch I didn't even need to the german version, after that nothing loaded, just like in your case.

I think some registry entry may be directed to a wrong path or messed up your registry by letting an ancient WIn2000 or something installation routine do its crappy work.

What helped in my case: I installed POP3D again on another system in the very same path (Like C:\GAMES\POP3d etc.)

Then I simply copied that folder via Usb Drive from that system to my main system, exchanging the messed up folder with the new one and it worked again.

Maybe worth a try?

@ Dalthnock & stealthjoe:

Funny, in my case I had best experiences with the regular 0.2.1. ddrawcompat for getting rid of any lag. The experimental/test release crashed on my system.

The 0.2.1 has only 2 problems on my PC: The movie files play a little jerky, with hiccups. I could get rid of this by setting the POp3d exe to XPSP3 compatibility mode.

The other minor problem with that version is, maybe related to me using the widescreen fix: It freezes when I quit the game.
This can easily be overcome by pressing STRG+ALT+DEL for starting the task manager, after that, I'm on WIN10 desktop again and it automatically shuts down. Still a little annoying, though.

Hi and thens for the reply!

The game no longer works on my main Win 10 Pro x64 desktop PC (Win build number 1809) but I installed the game on my Win 10 Pro x64 notebook (it was on build number 1803) and at first I tought that Windows build 1809 which is installed on my main desktop PC messed somethiung up but this game still works on my notebook even after updating windows to 1809 (same build number as my desktop). On my notebook I succesfully reinstalled the game multiple times to different locations with Revo Uninstalle and the "setup.exe" r and it still works.

I transfered my whole POP3D folder from my main PC to my notebook and the game starts normally. Really strange that it suddenly stopped working for no reasons on my main PC but it still works on my notebook no matter what I do.

BTW I should also mention that I didnt update graphics drivers in the meantime on my main desktop PC, Windows Update is not at fault which I confirmed already. Basically, all I did was uninstalling the game (english version) and QuickTime4 completely with Revo Uninstaller and installed the german version of the game and the game no longer works. Every time i double click the pop3d.exe it shows up in task manager for 1 seconds an dissapears/closes automatically without any error message..... its not even trying to go in windowed mode or fullscreen (not for a half second) , basically nothing happens when I double click on pop3d.exe.

So, maybe like you said the registry screwed something really up...... I dont know what else (nothing makes sense really), I will try your advice and report back.
