All,
I was wondering if anyone has encountered the situation as per the attached screenshot?
I have been able to setup all of Horizon App Manager's features except for the Windows Applications Network Share under the 'Windows Apps' section of the Horizon App Manager Connector.
Despite using a variety of different ways to access a Windows share (including FQDN for the host + share name, IP address + share name, d$ path directly to the location etc.. which being hosted on Windows Server 2008 R2) and the share having full read/write permissions for the service account I'm using (and, incidentally my own account I'm running the web browser), I cannot save the path as an access denied error is displayed as follows:
Problem configuring Windows Apps: RepoUpdateRegistry() failed with error: ERROR_ACCESS_DENIED :Access is denied
If anyone has experienced (and fixed) this particular error, I would be most grateful if you could share the solution!
Many thanks in advance! 
Paul
