When I launch AutoCAD LT 2002 as a non-Administrator user, it displays the error message
You do not have sufficient rights to run AutoCAD LT and then quits.
I also tried running it as Administrator once, in case it needed to perform some post-installation configuration. Now, when I log in as a non-Administrator user, it says
Failed to update the system registry. Please try using REGEDIT. and runs. But it would be nice to quell that error message.
