Sims 2 not working after downloading expansion pack

Downloaded the sims 2 open for buissness from here and installed it. Now when I just had the sims 2 (Also downloaded) I just mounted it to a drive on daemon tools and launched it no problems.
After downloading the expansion pack it just tells me to insert the sims 2 open for buissness disc, which I don’t have. (Because it’s downloaded) Even when I mount it using daemon tools it still says wrong disc, insert proper disk to continue.
Any help? I just want to play again.

Hi jackboy, I’ve had issues like this with other games before and personally I find it easier to use a No-CD crack, like an actual .exe file replacement, instead of having the mount an image. I have provided you with a link below where you can download the No-CD crack .exe file. Go to the link and find “The Sims 2: Open for Business v1.0 (v1.3.0.249) [MULTI] No-CD/Fixed EXE” and download that. As shown on the website, just go into the games directory and replace “<GameDir>\TSBIN\SIMS2EP3.EXE ” with the downloaded one.
