Sims 3 still don't work, really need help please. [SOLVED]

Hello!
Im back to the Sims 3 after a long break, so I downloaded TS3 and all expansions until Islande Paradise, I spent my evening yesterday to re-install all the games following step by step "How to install TS3 correctly"
But I always have the same error  whenever I tried to install TS3, when I ran the launcher it says :" An error has occured, please consult the readme for details" quiting launcher right after. I don"t know what to do with that, Im so tired of this message, anyone knows how to get rid of that?
Thanks alot.

Hi there!

Are you talking about this error, by any chance? 
https://games4theworld.forumotion.com/t6052-error-during-startup-see-log-for-more-details-fix

If you are, that post contains the fix for it.

And are you trying to open the Launcher after installing just the base game? Remember that the game won't work unless you install an EP or SP that came after Generations, including it. That's mentioned in the first step of the installation guide for TS3.

Good luck, and please let us know how it goes!

Thanks for the link, yes it's this error, I do install basegame+ all of the EP except back to future and movie stuff. Im gonna watch the video do what it needed and let you know!

I just did as it was explained on the video, I deleted the TS3 70's 80's 90's on the regedit, the only EP I didn't install and start the Launcher and get the same error 

Hello,

Please join the Forum's Chatbox when you see me online on the Forum. I'll try to solve your issue via TeamViewer.

Meanwhile: did you move, remove or rename any of the installed game folders?

Ok I'll try to catch you on, I didn't rename or move anything,I just followed the tuto step by step.

Problem being taken care of via Chatbox.

//EDIT

Apparently there were still two leftover values/folders in the Registry. I've removed those manually.
Problem solved, topic closed!
