Visual Studio 2008 SP1 installation failed on x64 Windows with Error 1324

If you’ve installed Visual Studio 2008 on an x64 Windows Computer you may getting into trouble trying to install Service Pack 1. First of all you will get an error message (Error 1324) which will tell you that Program Files contains an invalid character. After the installation finished you can access the log file. (shown below)

In there select the link (marked yellow).

And now search for pfiles. You will find something like G:\PFiles. On my computer G was a virtual drive. So the solution was to deactivate all virtual and physical read-only drives and then try the installation all over again. This time it worked seamlessly.
