Install SQL Server R2, tip error: An earlier version of Microsoft Visual Studio 2008 was installed on this computer. Upgrade Microsoft Visual Studio 2008 to SP1 before you install SQL Server 2008.

Install the tool when the VS2008 installed vs comes with the SQL tools, waiting for me to install SQL Server R2 when the "earlier version of Microsoft Visual Studio 2008" problem, found on the Internet solution is as follows :------for 32-bit systems (I am a bit of a 64-bit system this is all right.) Installing SQL Server R2, prompting for errors during installation: An earlier version of Microsoft Visual Studio 2008 was installed on this computer.

Some people say that it is to install SQL Server in the installation of VS, feel more tear, can not be removed, and later said to be asked to upgrade the Microsoft Visual Studio 2008 to SP1 before installing SQL servers 2008.

In fact, the solution:

Run the registry and rename the Hkey-local-machine/software/microsoft/devdiv on the line.

Install it and then change it back to OK.

------for 64-bit (successfully tried yourself)

Run the registry and rename the Hkey-local-machine/software/wow6432node/microsoft/devdiv on the line.

Install it and then change it back to OK.
