Installation problems for Visual studio 2008

Hi,

I have installed visual studio 2003,2005 in c:/ drive and Visual studio 2008 in
E:/ drive.

I have installed Visual studio 2008 correctly.Previously it was working fine.

By mistake i have deleted the installation files of Visual studio 2008.

Then,I have uninstalled  and installed Visual 2008 several time.i have formatted
the E:/ drive also.

 Then also it is not working. 

After installing visual studio 2008 ,Every time it displays "Successfully
installed " .

But ,while opening any project it displays "visual studio 2008 is not
installed properly.please re install Visual studio 2008"

Can any help regarding this Visual studio 2008 installation problem" ?

Hi

I think you have to remove its folder from the program file and also from the
registry settings ...
