Problems with Custom Installer - Anything I could still try?

So my problem is this:

I have a Sims 3 "Deluxe Edition" I downloaded for quite some time ago, which has one installer for multiple addons: Paradise Island, Generations, Ambitions, Late Night, Pets, Seasons, Showtime, Supernatural, University Life, World Adventures and bunch of stuff packs. I have read the thread "How to Install Sims 3 Correctly", but at the moment I can't gamble and download everything again one by one from here. So even though I can't follow those instructions by the letter, I thought to ask if someone knows what I still can do.

What I have tried was, at first, install the version 1.55 I had, then apply Patch I downloaded (from other site than this, because I did not find this then), and after that discover this site and apply the crack from the Ultimate Fix. However I did mess the installation up; game did update (after I downloaded DSetup.dll to fix it), and showed I had version 1.67, but started to act up when I tried to apply any mod with specific patch-requirements. If I used mod that needed patch earlier than 1.63, the game would crash at start up. If I would use mod that used patch 1.63 or later, it would crash when I tried to start up a new game. So what I did was uninstall and reinstall the game, downloaded the Manual Update from here and this time followed the instructions provided with ultimate fix as well as I could.

Only mistake I made was that I first installed the game to custom location, but moved it afterwards to the default path. Maybe that's the problem, dunno. But now the game wont start up at all. Both Laucher and the .exe give same error:

 

So I did test the game earlier and without update it worked fine, so I can give up few mods (sadly) and use only what I have; but if someone knows what I could still try, I would be most grateful. I know I have not done as I'm told to but I at the moment I feel it is too risky...
