Tried Disable visual effects . run as Admin , installing on a different drive … and on a different win 7 machine . Then installed on a W10 machine and it exited fine no messages . Any fixes would be greatly appreciated .

Prepare for disappointment, since Winows 7 is an unsupported system since january 2020. Don’t expect fixes for that.
