I have been installing TMG for a couple of machines already and this is the first time I have encountered this issue. The installation wizard stops at the "Additional Components (Estimated time: 12 minutes)", and prompts the error message:
"Microsoft SQL Express 2008 (reporting instance) could not be installed. As a result, Forefront TMG installation cannot be completed."
I have tried uninstalling SQL from this machine, reboot, and reinstalled it, then install TMG again, but it still prompts this error message.
I am at a lost on how I should go about with this actually. Anyone has any suggestions?
