I'm trying to install the update for my graphics card drivers but am having problems. When it starts the install, the first thing it tries to install is the install manager, even though it says my version is up to date. When the installation starts, it hangs up immediately at 2% during the installation of the install manager. When I restart the install and try to uncheck 'install install manager', it won't let me, it's greyed out. So not sure what to do.
