How to Fix Error 1722by Greyson Ferguson
Microsoft has categorized all the errors that occur on Windows by giving each individual error its own number. One such error is "1722." Error 1722 occurs when you attempt to reinstall Microsoft Flight Simulator X Deluxe or Standard after it has already been installed and removed at a previous time. The second installation will not take place, and the error 1722 message will be displayed. The good news is that there is a Microsoft download that can fix this issue.
Follow the link to the provided Microsoft support page (see Resources).
