Here’s how i got SQL Server 2008 Management Studio installed on my Windows 7 32bit Laptop.  There are problems with Windows 7 because support was not available in the initial release.  You could either slipstream Sp3  or do the following:

1.       Go to the root of the CD and right click “Setup.exe” and “Run As Administrator”

2.       Ignore all messages regarding incompatability and just continue

3.       Choose the following under the installation menu


4. Then get to Feature selection and choose the following

5.       Continue with the install

NOTE: 9/13/12 – I had to run the above 3 or 4 times before it actually let me perform the install. So be patient.

6.       While it’s installing download SQL Sp3 from here

7.       Install the SP3.

That’s all I had to do to get this to work. Should be under Microsoft SQL Server 2008 in your start menu.  You might also want to install the Business Intelligence Development studio, but that’s up to you.
