I did a factory reset of my desktop PC last month. DirectPlay is installed and enabled. Not sure why it won't run now when it worked last year.
I get a screen that says "Firaxis Games" and then it crashes. I already tried uninstalling and reinstalling Alpha Centauri.
Here is the link to the GOG.com techinical assistance page. Try these to see if any fits or can fix the issue of crash at startup. https://support.gog.com/hc/en-us/articles/213517609-Sid-Meier-s-Alpha-Centauri-Planetary-Pack?product=gog
I read some other topics in this forum area and one of the people who was crashing at the same point as you needed to update their graphics drivers. Once they did that the game started up just fine.
I ran the AMD Radeon Software auto-updater but no change. I am using the recommended Microsoft-certified AMD Radeon version, and not the newest optional AMD Radeon version. All other Microsoft and HP updates are up-to-date. I put in a support ticket to GOG, but could be weeks until I get a reply. I am on the HP Pavilion 690-0010 with AMD Ryzen 2200G CPU (32 GB DDR4) and AMD Radeon RX 550 GPU (4 GB GDDR5).
Running as Administrator and running with Windows Program Compatibility Troubleshooter (directly from Windows File Explorer) does not work either. Always the same result: loadscreen says "Firaxis Games" for about one second and then crashes.
If anyone else using AMD graphics on Windows 10 has the same problem, it could be that the newest AMD graphics may no longer be supported, if it used to work, and doesn't work now.
