Sync fails, no notification, log shows "failed to open: <filename>"
I'm syncing three PCs via Backupper Pro 6.3.0. Two PCs sync without trouble, but one failed to sync last night. Backupper shows the following message for a number of files in the AppData/Local folder:
Failed to open: C:\Users\<username>\AppData\Local\Microsoft\WindowsApps\B9ECED6F.ASUSPCAssistant.AsusKeyboardHost.exe. Result: 1920.The sync does not occur, but there is no log entry showing that it failed, and I don't get any email notification that it failed. Any idea what the problem is?
