Windows: Auto-updating fails (Error: spawn [...].exe EACCES)

[kraenhansen]

• Version: electron-builder v20.35.0, electron-updater v4.0.0 and electron v3.0.8

• Target: Windows (NSIS)

Auto-updating fails. To me it looks like the updater stores the new version executable in a location from which it doesn't have access to execute. When I run the application as an administrator the update + install works like a charm. So ... to me it looks like a regression of #1129.

This might be a duplicate of #3367 but I wanted to make it obvious that it happens with the most recent versions too.

Also #1580 (comment) suggests that this might happen when nsis.perMachine is set to false, but it is set to true in my package.json.

This is the STDOUT of my application while performing an update:

Checking for update
Found version 3.0.6 (url: Realm Studio Setup 3.0.6.exe)

updater cache dir: C:\Users\IEUser\AppData\Local\realm-studio-updater
Update has already been downloaded to C:\Users\IEUser\AppData\Local\realm-studio-updater\pending\Realm Studio Setup 3.0.6.exe).

After I click my dialog to accept the new version.

@kraenhansen Thanks for using pre-release versions. Regression was fixed. Even more — now electron-builder stores information that UAC is required for installer as part of update info, so, first always failed spawn now will be not performed at all.
