I had the exact same problem until I downloaded Sims2Pack Clean Installer.  You can get it here, http://sims2pack.modthesims2.com/.  You run the program and search for the files by using the browse option.  It then should then be able to turn the SIMSLSPACK files into compatable package files for the game.  However, even after I did this not all of the files that came with the welcome pack installed.  I'm not sure why, hopefully someone who knows more about this kind of stuff can help you out.

I assure you I did not pay for them, however, I did recently update my game.  Kind of strange how they got there though...

That is pretty  nifty!!  Thanks

I was playing my game a minute ago and decided to buy my teen girl some new clothes.  When the screen popped up to buy the clothes I noticed two outfits that I have never seen before (or at least haven't noticed before).  I thought maybe they were custom content but there wasn't an '*' on the picture to say it was custom.  So basically my question is did this outfit come with the game or did I somehow download it??  I don't ever remember seeing it so I am confused.  Thanks guys!!  

  THANK YOU SOOOO MUCH ENGRAM!!!  It worked!!  Thanks soooo much!! 

Alrighty I did what you said and the sim still doesn't show up, however the custom content from the sim does.  I guess that is better than nothing... 

Oh ok I am going to go try this.  I hope it works!!

Oh darn.  From the way the sticky above was talking I didn't think I would need TS2.  Oh well, I tried.  Thanks a bunch!

I don't have The Sims 2 installed on my computer, just Sims Life Stories.  Will this still work?

I was reading the forums here and saw in the sticky above that I could install sims into my SLS game if I used clean installer.  I went ahead and installed clean installer and downloaded a .zip file of a sim from TSR.  I then opened clean installer and it turned my .zip folder into a sims2pack file.  I then double clicked on it and installed it into my downloads folder.  I started the game and went to CAS but the downloaded sim wasn't there.  Am I not putting the files in the right place?  BTW, when clean installer asks to select a file extension should I choose Sim2Tmp or package?  I am really confused and would love to have downloaded sims.  I made sure to use a sim that was base game compatable btw.  Thanks for any help.

Thanks to both of you.  I did get rid of insim after I got that goal met and I think I am on chapter 11 now and everything is good.

Thanks, their lifetime relationship was actuallly 100 and still no hit-on interaction.  I downloaded the insimenator and set their realationship back to friends and then tried again and for some reason hit-on showed up.. Very strange.  Now Im having the same problem with Dylan, they both have a lifetime relationship to 100 but still no interatction to have a romantic kiss.   I guess I will have to do the same thing.  But i will check the link out too.

I bought The Sims Life Stories a few days ago and I am on chapter 2.  Riley now wants to Hit-On Mickey, but this option is not showing up.  I have kept her talking to him and flirting with him and they are now in love, but the 'hit-on" option will not show up.  Mickey now just sticks around the house until about 3:00 a.m. and then comes back at 7:00 a.m. and just walks around the house.  He will not leave and she still can't 'hit-on' him.  It is starting to get annoying because the story can't progress.  I would say 4 or 5 sim days have passed and nothing is happening.

Any clues as to why the 'hit-on' option isn't showing up?  I get all the other flirt options except that one.  I appreciate any help!  Thanks!!
