Explain to me why i could only load up Entrenchment and not the original Sins of a Solar Empire version 1.12.042?

I checked on Impulse to load up SoaSE only to find Entrenchment available, I am aware that Impulse runs in the background, so I'm assuming Impulse does some background updating. I'd prefer it if i had a choice of either playing Sins of a Solar Empire version 1.12.042 and Entrenchment version 0.91.002. I've had to yet again uninstall and reinstall SoaSE and Entrenchment, It's very inconvenient for me.

I don't like that. Not at all.

I'd prefer not to have to open yet another ticket with Stardock support.
