It seems like you have installed an unofficial modification...:((

Hi all,

I just updated my patch to the latest version 1.63.5 and applied the ultimate fix and everything. However, when I started the game this pop up appeared.

"It looks like you have installed an unofficial game modification that does not match your current version of The Sims 3. We recommend that you either uninstall these game modifications or get updated versions of them - otherwise you may experience crashes or significant bugs"

Please help!!!

A little background info. I have pets, generations, ambitions and university life installed. It was working fine before the 1.63.5 patch. I applied the ultimate fix to the base game, ambitions and "all expansions after generations" and the crack after manually patching.

In my previous version before I patched to 1.63.5 I had the errortrap and overwatch mod applied. However,  I removed the entire Mod folder before following through with the ultimate fix and applying the manual patch.

I have tried renaming the Sims 3 folder in documents but the message still pops out:(

PLEASE HELP ME! Will appreciate it sooo much. Thanks!

did you put the mod folder back? cause it sounds like you have outdated mods  on pc.

I took the entire Mods folder out but did not put it back

Well, i found this. Maybe you can refer to this . Also make sure that the ultimax fix is the latest and all the sims file is get from g4tw.
Besides, i also check from other website that you can uninstall all the game and reinstall it and see how it works. Before that, you try to run the game and see it work or not, if it is, maybe you can just ignore the notification ...

hmm which expansion shoud I uninstall?

btw, does anybody have just the crack files in seasons EP? I am trying to reinstall but I realised that i removed the files in the crack folder the previous time I installed. And I dont want to re download the entire rar file again!

What you need for the crack file ? 
Erm, you try download the latest ultimate fix and apply it correctly according to the guideline.

By the way, is your sims file get from here? And  This is the ULTIMATE crack from g4tw
