I am trying to install a 256mb x300SE on Windows XP SP3 32 bit, and when I try to install it says "Setup will only run in Administrator mode, setup is aborting".
I am logged in with the Administrator account, the machine is not joined to a domain. I have tried installing via the setup.exe file, the setup in the driver file subdirectory, directly adding the driver file via Device manager, all of these both in a normal login and in Safe Mode. I have tried compatibility mode, Run As, running it as a different Administrator level account, and sacrificing a small goat. Nothing is working.
The closest I can get is adding the driver via Device Manager, but then I get a "Device could not be started" error. The device itself seems to be fine, I'm typing this in VGA mode on the machine, but I can't get the driver installed.
Further, when I try to download a legacy version of the drivers via http://support.amd.com/en-us/download/desktop/legacy/previous?product=legacy2&os=Windows%20XP%20-%20Professional/Home&RenderOnServer=true, I get a list of 2 previous versions, but neither has any clickable link anywhere in the page that I can find, both in Chrome and IE.
I would appreciate any advice that could get this driver installed, or a link to an older version of the driver file that works.
