IMPORTANT!!! Make sure you using the latest driver for your graphics card! Otherwise SpaceEngine may not work or work incorrectly.
1) Download the zip archive using the links above.
2) Make a copy of your SpaceEngine 0.9.7.2 folder and rename it into 0.9.7.3.
3) Unpack the downloaded file into this new folder, overwrite existing files.
* You may just unpack the archive into your SpaceEngine 0.9.7.2 folder, but this will overwrite your locations, wiki database and other files.
Copying to another PC
SpaceEngine is a portable application. You may simply copy all contents of the SpaceEngine folder to another location and run SpaceEngine.exe, located in the system subfolder. You should not copy the "cache" subfolder though - it is created automatically.
Install process isn't bad. Just download and run the SE-0972-setup to get v0.9.7.2. If you want to upgrade to the new version, then just download SE-0973-patch and extract it in the SpaceEngine install directory.
I have v0.9.7.3 working on my Windows 10. You have to run the program as administrator though or it won't start. And at first it was crashing at startup, but then read the FAQ. If there is a \SpaceEngine 0.973\system\atioglxx.dll file, delete it. After I did that and restarted SpaceEngine (as administrator), it is now working on my Windows 10.
I was able to get this game working on Ubuntu 14.04 and Wine from my server box which has an Asus 9600GT with 512MB of ram. I'm happy to say the game works fine and graphics looks awesome even for this old card.
You should be able to make it work with Win8. I did. After installing, right click on the icon and go to Properties. Go to Compatibility. Try either clicking on "Run compatibility troubleshooter" and go through that, or under "Compatibility mode" try checking "Run this program in compatibility mode for:" and change the drop down from Windows 8 to Windows 7 or another Windows. See if that works for you! :-)
