32-bit W7 and SQL Server 2008 Management Studio Express

Installation fails. Google finds some "solutions", but they don't help.

TITLE: SQL Server Setup failure.
------------------------------

SQL Server Setup has encountered the following error:

MsiGetProductInfo failed to retrieve ProductVersion for package with Product Code = '{AEB9948B-4FF2-47C9-990E-47014492A0FE}'. Error code: 1608..

BUTTONS:

OK

In this folder, there is only one file - ARPIco, 6 kB big.

Anyone with the same problem and a simple solution?

I followed Henrik Bruun's steps:
