running win7 and get an error 1603 during install; looked at the log files and did see where it mentions "old path found" before it starts to uninstall. ill attach the logs.
Solved! Go to Solution.
got it to run without an error
originally ran from autocad 3d to run service pack. found exe in the temp dir and moved to c drive. ran from there as administrator and ran successful. also did a cleanup of temp folder for kicks because it needed it. one of the 2 corrected the error.
