installing rush hour on vista

[pjclmnsn 0]

Hi guys 
im so frustrated! i can get sim city 4 by itself to install and play fine on the new laptop but when i go to install rush hour it stops at 59%, then after a while it comes up with "unable to locate required file or required file is corrupted." i bought the 2 separately (sc4 and rush hour) - and saw someone elses post (from '05) and said they had exactly the same problem but did not have a solution so anyone your help is much greatly appreciated!!! have also tried changing compatibility to xp but no luck as yet.
System: 
Dell studio
2ghz dual processor, 2mb cache
vista home premium 32bit
256mb ati radeon
3GB RAM

installed fine on my last XP computer so im kinda sure its not the cd.

I had this problem a couple of years ago, but on XP. I solved it simply by ripping the contents of the affected cd, deleting the affected file then copying another file and renaming it to that of the corrupt file. Once the altered disc had been burned it installed and has worked fine ever since (on xp, Vista and Win7). That may not be true in this instance though depending on which file it is having trouble with, so it's best to maybe compile the new disc to a disc image and mount it to see if it installs and works before burning it. Your only other alternatives is to other buy a new copy or "source" one from the interwebz. You might also want to check that its not just a dirty cd.

I had this problem also but was solved fast. I had another computer that had Windows XP.I installed SC4 Rush hour in this computer. Afterwards, I copied the whole file of the installed SC4 from my computer to the other computer that has Vista. It worked without glitches..
