Hi,
Here the QTP version is same and browser version is same(i.e. QTP 10,IE8) but Operating system is different.(i.e. XP & Windows7)
There is nothing to do with Object repository in this case.
HP provided a patch (QTP_00644.exe) for QTP 10 inorder to support "Windows 7" operating system.
Get the patch > install it > check once > you can get it resolved
