Vista - The Sims 2 installaition on my pc?

Hi,
I had a Windows XP, with the xp theme, pointers, backgrounds, screen savers etc, and i had the sims 2 installed on it, it was working good, but a bit slow, i sent my computer to get formatted, when i got my pc again, some changes were on it, it changed to vista screen savers, wallpapers, pointers and theme, but when i opened Start and chose run and typed DXDIAG, i still see windows xp pro, and my system became Black xp and the formatter installed Vista Inspirat 2 1.0, when i installed the sims 2 again, it reaches 1% and (an error occurred while copying the file (***/***/***) from the media. press retry to retry copying the file or cancel to cancel the installation)
When I press retry, the same window with the error appears again, again, again and again. When I press cancel the installation cancels. What should I do? Should i uninstall the vista inspirat, or the sims 2 wont work on my pc?

Try uninstalling the Vista Inspirat. Sounds like that changed and your problems started. probably just incompatibilities.

I did, i uninstalled it, but no changes, the thing im trying to remove is that when i click on right click, i dont want to see those options: (run vista executable/patch and run vista executable) but i dont know how, ill format my pc soon i think this will solve my problem.

That would solve the problem, but it will lose a lot of your data. Only do that if you dont have another choice. Try opening add/remove programs, and uninstalling the Vista thing from there.

Don't worry about my data, i have a lot of flash drives to store whatever i want. but i don't hav any "VISTA" name in add/remove programs, thanks for the help.

All right then. Let us know how it turns out!

Why do you have to format again your pc if you actually sent it 'to get formatted' ....??
Anyways, if you think you have to format it, be sure to install all drivers again one by one before trying to run the game.
motherboard,video,sound, and all the drivers you could need.
And for some intel processor there are some 'application accelerator' availaible which increase your cpu's speed.search the right one with google or on intel website.
