Hey i upgraded from XP to Windows 7 64 bit and now i can not install the Construction set on my computer. Is there anything i can do to get Construction set working again.

Where did you install the game ?? -- In Vista and Win7 MS increased the security level of the Programs Files folder so that virii etc. could not modify your programs (and as far as the OS is concerned that is what the CS is trying to do !) --- files written to that folder are actually redirected to a user specific folder instead and older games like OB do not always work properly if installed there ! --- try reinstalling you game to another folder (ie. C:\Games\Oblivion or similar) so that they are not redirected and it should work fine (there are a lot of people using the game and CS under 64 bit versions of VISTA and WIn7 so it can work)
