When the App-V 5.0 Management console is installed on a drive other than the C: drive, launching the console may fail and generate the following error message:

HTTP Error 500.19 - Internal Server Error
Module IIS Web Core
Notification Unknown
Handler Not yet determined
Error Code 0x80070005
Config Error Cannot read configuration file due to insufficient permissions 
Config File \\?\E:\Program Files\Microsoft Application Virtualization Server\ManagementService\web.config


This occurs due to invalid NTFS permissions on the drive hosting the App-V 5.0 Management Service INSTALLDIR directory.


To resolve this issue, give the local computers Users group Read & execute, List folder contents and Read permissions to the root of the drive the hosts the App-V Management consoles INSTALLDIR directory. The INSTALLDIR parameter can be found referencing the following registry key:


The local computer User group contains the following users by default:

Local Administrator Account
NT AUTHORITY\Authenticated users (S-1-5-11)
Domain\Domain users

After updating the permissions on the drive that hosts the INSTALLDIR directory, either stop and start the Microsoft App-V Management Service website in IIS or issue an IISRESET.
