After installing the latest Windows 10 update (the Fall Creators Update) Sage 50 is crashing when launching certain tasks. The solution, until Sage releases a patch, is to run Sage 50 in compatibility mode for Windows 8. Just follow these steps:

  1. Right-click the Sage 50 Accounting icon on your desktop and select properties.
  2. Click the Compatibility tab.
  3. Check the box located in the Compatibility mode section and select Windows 8 from the drop down menu.
  4. Click OK to save your change and close the Properties window.

Launch Sage 50 from the desktop icon and it should work like normal again.

You may have problems emailing invoices, reports, etc. from Sage 50 using Outlook when you have set Sage 50 to run as administrator. If that happens you’ll also need to set Outlook to run as administrator.
