SP1 for Visual Studio 2008 has progressed from the Beta workbench. It is now publicly available for download from Microsoft.
If you have installed the Service Pack beta you will need to install the following Service Pack Preparation tool before installing SP1. Note: With the preparation tool you may be required to insert your original Visual Studio 2008 installation disk.
The only issue I had was while performing the preparation tool where an MSI file ‘rdbg_std.msi’ was ‘missing’. I found out that it was ‘Remote Debugger’ related, then looked for the relevant file on the Visual Studio installation disk. It was under <cd>\Remote Debugger\x86 (or x64)\rdbgsetup.exe. I had WinRAR installed so I right clicked, and extracted the file which resulted in the creation of a ‘rdbg_std.msi’. I pointed the installation to that file and all was good.
Should you have any other issues installing the Service Pack, take a look at the read me. It contains some troubleshooting material and installation details.
