I was not able to successfully install Visual Studio 2010 Beta 2 x86 on my Vista SP2 x64 computer. I selected all options except SQL Express 2008 (I already have the full server). It first hung at one of the two "Data-Tier Application Component xxxxxxx" steps (I don't remember exactly which one) and even the sliding flash on the progress bar was locked. I had to log out to kill the installer. I tried to start the install again, and it said I needed to reboot because there was an install in progress, so I did. When I got the installer started again, it picked up after the "Data-Tier Application Component xxxxxxx" steps. The progress bar for the "Microsoft Visual Studio 2010" step got about 1 mm from the end, and then it hung with "Executing action: VsaEnv_Setup_x86_enu." But this time the sliding flash kept sliding. I rebooted and tried the installer again. This time it offered the "Repair" option so I tried that. I only offered the componenets up thru "Microsoft Visual Studio 2010" as that is all the farther it go on the install passes. It again hung at VsaEnv_Setup_x86_enu. Now, after another reboot, I have tried uninstalling, and it has hung at "Executing action: VsaEnv_Setup_x86_enu." All the buttons, including the window frame buttons, are grayed out except for the minimize button. This is a bad situation where I cannot install it, and I cannot uninstall it. To a certain extent, my computer is now damaged.
