sounds like you might have another issue with the computer if it wont load an exe file
But there could be multiple reasons for the scanner not completing
Before we try to sort that out. If it used to work recently try doing a system restore to a time when it was working. Make sure that you select a date when it was in fact working you might have to click the box to show more restore points
System restore instructions - windows 7 or 8 or 10
hold the windows logo key down and hit R
type rstrui.exe in the run box that comes up and hit enter
select restore to an earlier date.
Under the "suggested restore" which is usually not old enough to help is a link for "OTHER RESTORE POINTS"
click that if the suggested ones are not BEFORE THE PROBLEM STARTED
choose a date that is BEFORE you experienced the problem
hit ok / restore
the computer will start to shut down
a restoring settngs box will appear with a status bar
when it finishes your computer will restart with the same settings it had on the date you restored to. your data will not be affected.
It is not perfect. But it fixes a lot of things.
