Ahhh.... okie, let me go slow, haha, so i dont confuse myself.
1. Uninstall the game.
2. Install 1.05 to D: drive.
3. Copy game folder C:\...\Stardock Games\Sins of a Solar Empire\etc... to C: drive.
4. Start copy from the C:\drive and log into Impulse.
5. Update copy on C:\ drive.
?? Hmmm.... haha, well... i guess if i want "both" haha. 
Thank you to all, i appreciate your time. Thank you. I will give it a try and let you know how it goes.

Unless it "see's" the other copy and wont let me update, haha, software that is self-aware. You got to love it!

Thank you,
Sincerely,
