A few months ago Microsoft released an update to Windows 10 that caused Sage 50 to crash. But you could work around it by setting Sage 50 to run in compatibility mode. Now Microsoft has released a new Windows 10 update that is causing Sage 50 to fail to open when it is set to run in compatibility mode.
Fortunately the conflict that forced Windows 10 users to run Sage 50 in compatibility mode has been resolved. So if your Sage 50 suddenly won’t open after installing the latest Windows 10 updates, the fix is simple.
Right click on the Sage 50 shortcut on your desktop and choose Properties. Go to the Compatability tab and clear the check box next to “Run this program in compatibility mode for“. Click OK to save the change.
If you haven’t restarted your computer since the last time Sage 50 failed to open, then it’s still stuck in memory and you won’t be able to open Sage 50 until you clear it. The simplest way is just to restart your computer. If you want a quicker method and are familiar with using Task Manager, you can go to the Details tab in Task Manager, find Peachw.exe and click End Task.
