Sims 2 University Installation Error - Please Help!!!

Archived from groups: alt.games.the-sims-2 (More info?)

I have recently bought the Sims 2 University. I have tried to insall it
many of time and have had no luck! It seems to install ok but when it
checks that the Sims 2 is up to date and asks you to put in CD4 it pops
up with a box that says...

"The update proccess did not complete successfully. Installation will
now terminate."

I have read a few posts which told me to uninstall The Sims 2 and then
reinstall both - this din't work. I have also removed all traces of The
Sims 2 ever being on my PC including searching for and deleting anthing
related to the sims 2 in the registry - this, again didn't work.

I have well and truly run out of ideas and to be perfectly honest I'm
not sure its really worth the hassle! But when you pay £20 you want it
to work.

I am running Windows XP, with plenty of RAM and Proccessing power.

Any help would be greatly appreciated.

Dan
