10. WindowsIoTCoreWatcher.exe does not start and how fix it

Sometimes after you install the Windows IoT core Raspberry Pi 2 SDK, you may find that the monitoring tool “Windows IoT Watcher” cannot be launched. If you start to research you’ll find the following error

Could not load file or assembly ‘ WindowsIoTCoreWatcher, Version = 10. 0. 0. 0, Culture = neutral, PublicKeyToken = 31bf3856ad364e35′ or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A)

And of course, working with a Preview OS, with an SDK also in Preview, the most advisable to do is go to the forums to find some help.

I I found several people in the same situation and with a not so elegant solution (but it works) “remove the app certificate“.

To do this, we use SNRemove.exe, an interesting tool created 10 years ago! with the following command

“snremove.exe – r WindowsIoTCoreWatcher.exe“

And ready, now we can launch without a problem the app. Here is the curious Friday tip.
