I have uninstalled and reinstalled to no avail.
It just won't run; No error msg but it won't run. I can see a cursor but no music or anything else, except the "black scrfeen of death". When I go to Task manager to clear things out, I see this minidump listed, which may be significant in the light of some of the previous threads.
I am both disappointed and surprised.
Two previous Stardock Gal Civ games I have installed and played with no problems and the very box of Sins of a Solar Empire proclaims it "Games for Windows" and yet it cannot, apparently, handle Windows 7. Curiously enough, it is supposed to be according to Windows compatible with Windows 7 64 bit but it ain't! Not on may machine.
Pity, I badly wanted to try out the Star Trek mod. Still, I shall keep a weather eye out on forum until there is patch advertised which makes it play under Windows 7 - for I can see I am not the only one with problems.
Live long and prosper.
