This article provides a solution to an issue where launching the App-V 5.0 Management console that's installed on a drive other than the C: drive fails.

Applies to:   Windows Server 2008 R2 Service Pack 1, Windows 7 Service Pack 1
Original KB number:   2800730

Symptoms

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

Cause

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

Resolution

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:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppV\Server\ManagementService

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

  • Local Administrator Account
  • NT AUTHORITY\Authenticated users (S-1-5-11)
  • NT AUTHORITY\INTERACTIVE (S-1-5-4)
  • 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.
