I'm pretty sure it's because of the folder name [Emulators] , those characters should cause problems [ ]
If you can try putting the emulator in another folder and try updating to make sure that this is what is causing the problem

Confirmed, that is the cause of it failing to update.

PowerShell's Expand-Archive function does not handle [ ] characters well.
A temporary workaround is to not save the emulator inside folders with these characters.

A proposed solution would be to change the code to download the update to some Windows temporary folder instead of 'user\temp_download_update'.

To do this, you would have to change the paths in check_update.cpp in DownloadUpdate() and in Install().
I don't have much time for this, if any developer is interested in solving this...
