sims 3 there was an error during startup please see the log for more details

I also have to add, it took a few seconds to start up - I didn't think it worked at first but after about 10 seconds it started.

I was just about to give up and tried your solution. Thank you! This worked for me. For me it was under Libraries/Documents/Electronic Arts. Now it lets me go to the launcher to update the game.

my file was already named TS3.exe and I am getting the same error message.

i had this same problem, no solutions worked. then i discovered the problem is in the registry! the base game entry in the registry is pointing to the wrong location! i also recommend you note down the location that it thinks its in becuz your update files will probably be there and you'll have to move them manually!

i think the update patcher does this if your game is installed anywhere other than the default location which is C:\Program Files (x86)\Electronic Arts\Sims 3 if i remember correctly

incase you dont know or forgot

• Expand the HKEY_LOCAL_MACHINE folder.
• Expand the SOFTWARE folder.
  • For 64-bit systems, expand Wow6432Node
• Expand the Electronic Arts folder.
• Expand the Sims folder.

The same thing happened to me, and this really helped!

This is a frustrating issue, but I suggest that before you spend hours un-installing re-installing and messing around with your registry and such try clearing the game cache files first.

1) Go into your main boot drive and go into the Users folder - find the folder matching your account name and go in.

 

2) Once inside go into: Electronic Arts / The Sims 3 / DDCache

 

3) Delete missingdeps.idx

 

Then finally, cross your fingers, and try running the launcher after this.  Good luck!
