What you need to do is install Sims 2 then manually patch Sims 2 base game from the Mod the Sims patches page. THEN install University and then apply the University patch from MDS. It will check each time to see if you are patched but it will immediately say you are up to date and then successfully complete. Install each expansion in order and the proper patch for each expansion immediately thereafter. Please note, there is only one stuff pack (Family Fun Stuff) that requires a patch. This immediately precedes installing the Pets expansion which will be looking for this update when it’s finishing installing. As long as you have it applied, Pets will pass and you can continue on. For this reason, it is crucial that you apply the games in order as listed above. The reason for this is to ensure you have each expansion/stuff pack’s patch properly installed FIRST.
I’m installing them all myself today and am having no trouble using the above method. Prior to this, I couldn’t even get past University. I did install the “don’t look for updates” patch someone listed after installing base game but I don’t think it’s necessary because as soon as you apply Sims 2 base game patch, it must overwrite it as it does look for updates (but you’ll already have them installed so it will see that and let you proceed).
