I'm trying to install CAW and has found a help page I think is right. I need to install 1.24 patch because I have already tried and got this error message about invalid file. I tried installing CAW before that, and got errors about game not updated.
http://www.modthesims.info/wiki.php...alid_File_Error

I run the last program for net 3.5. I'm not sure that's right but it produced this file error for me: Update for game\bin\packs TS3SP04\paul.dll Error: err0031 - invalid file found.

So I'm suppose to follow this "how to restore ..." subject.

I'm a bit I don't find a file named "Sims3Launcher.exe" in my Sims3\game\bin.
I find "Sims3Launcher.exe.config". I can't find any straight .exe file in there. Is this the right file?

What patch file did you download? Not the SuperPatcher from here? Game_Help:TS3_Patching:Patch_Download/Current^wiki
And if you don't have Town Life Stuff as your last installed pack, you need to do the workarounds for CAW as shown in Game Help:Patch_Table^wiki - see the link to the Talk page.

For future reference, Sims 3 related issues belong in Sims 3 Help, Comp Tech + Software Help is for non-Sims Computer Problems, as the Announcement states. Thread locked.
If you still have issues after using the SuperPatcher, post in Sims 3 Help, please. Thank you.
Since you've posted there before, you know where it is.
