Auto run sims 2 won't work on stuff packs after i downloaded the holiday pack

After i installed the holiday stuff pack, when i go into the next file which is h&M fashion stuff, I try to click the autorun.exe, but nothing happens. I tried closing the folders and reopening it, but it still won't work. I even tried doing the next one which is teen style stuff and skipping to the last one, but none work.

Note: i am installing them on an external hardrive cus there is limited space in the c drive. the holiday pack didnt ask for a location like the others did.
