Is there a simple solution that allows for the updates with prompting the user and without having to install to folder other that the one above?
In wyUpdate 2.6.18 we're making the detection of ACL settings of folders. That is, if you make a limited user have the correct permissions (Read, Write, Execute, etc.) to your install folder (C:\Program Files\Your App) then wyUpdate will be able to update your app without requiring admin permissions.
I can send you the current version to your email if you want.
as we have no control over the installations and/or the associated folders apart from at install time.
That's when you set the ACL of the folder: at install time.
The other alternative is to create a dummy Windows Service that has the singular job of updating your app. See: How to Silently update a Windows Service or AutomaticUpdater tutorial for Windows Services and Console Apps.
