User interface not appearing when launching Garmin Express on my Windows 7 laptop started a few days ago.
Express.exe does get started as a process (as seen in Task Manager) but user interface does not appear.
Same no-user-interface problem when launching Garmin Express manually or when it is setup to automatically launch when a Garmin device is connected to USB.
I went through all the Garmin Support document steps to try and resolve this, including full uninstall and reinstall of GarminExpress.
I examined the Garmin logs in CL\ProgramData\Garmiin\Logs\Express and they had error:
System.BadImageFormatException
Could not load file or assembly 'CefSharp.Core.dll' or one of its dependencies. is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)
at Garmin.Omt.Express.App.<Application_Startup>d__14.MoveNext()
I google-diagnosed this and seems CefSharp.Core.dll is part of the Microsoft Visual C++ 2015-2022 Redistributable (x86) component. I noticed the GarminExpress install includes an install of this product, so I did a repair install of it through the Control Panel->Programs and Features. No interface issue remains.
Just wondering if anyone else has experienced this issue. The same GarminExpress 7.19.00 version works fine on my Windows 10 laptop.
