Thanks for sending that over. We currently don't have a way to auto update the path if the version number changes, but I've added this to our list to look into. We'll be sure to let you know if we have anything further in the future.

Thanks! ]]> https://www.displayfusion.com/Discussions/View/application-failed-to-start-file-not-found-win10-mail-and-calendar/?ID=efef4afe-a317-410c-9b8a-40e3a1569fb5#5 Wed, 01 Sep 2021 16:08:29 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/application-failed-to-start-file-not-found-win10-mail-and-calendar/?ID=efef4afe-a317-410c-9b8a-40e3a1569fb5#5 DisplayFusion Hi Owen,

Attached are the screen shots for loading mail and loading calendar.

Could you send me over a screenshot of the function you're using to load those applications?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/application-failed-to-start-file-not-found-win10-mail-and-calendar/?ID=efef4afe-a317-410c-9b8a-40e3a1569fb5#3 Tue, 31 Aug 2021 18:25:22 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/application-failed-to-start-file-not-found-win10-mail-and-calendar/?ID=efef4afe-a317-410c-9b8a-40e3a1569fb5#3 DisplayFusion Hi Owen,

I don't have mail pinned to my taskbar but it is on the start menu. I do have calendar pinned to the windows taskbar. After an update, both of those work ok, though for mail it doesn't put it in the right window and its maximized across both windows on Monitor 1.

Background: I have 3 monitors.
Monitor 1 27" split into 2 windows
Monitor 2 55" TV usually turned off
Monitor 3 Old 19" monitor (Main Display)
Calendar is on Monitor 3.
Mail is on Monitor 1 Left window when everything works correctly.

After an update, DF cannont find either app and I have to go reset the DF function to load mail and calendar.

Let me know what other info you need. ]]> https://www.displayfusion.com/Discussions/View/application-failed-to-start-file-not-found-win10-mail-and-calendar/?ID=efef4afe-a317-410c-9b8a-40e3a1569fb5#2 Tue, 31 Aug 2021 16:59:32 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/application-failed-to-start-file-not-found-win10-mail-and-calendar/?ID=efef4afe-a317-410c-9b8a-40e3a1569fb5#2 DisplayFusion Hi Stan,

Is this happening when launching an application from your taskbar?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/application-failed-to-start-file-not-found-win10-mail-and-calendar/?ID=efef4afe-a317-410c-9b8a-40e3a1569fb5 Sun, 29 Aug 2021 15:53:31 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/application-failed-to-start-file-not-found-win10-mail-and-calendar/?ID=efef4afe-a317-410c-9b8a-40e3a1569fb5 DisplayFusion Application failed to start, file not found.
C:\Program Files\WindowsApps\microsoft.windowscommunicationsapps_16005.14326.20090.0_x64__8wekyb3d8bbwe\AppxManifest.xml

This happens everytime Microsoft updates the app. Is there a way to make the trigger permanent? ]]>
