This is the error i receive when i build the GuestBook demo. Does anyone have any idea what would be causing this? I’m assuming something got installed wrong but i can’t figure out what. I’m also assuming it has something to do with MSBuild.

Error   1   The "DeleteCurrentDeployment" task failed unexpectedly.
System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.VisualStudio.OLE.Interop.IServiceProvider'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{6D5140C1-7436-11CE-8034-00AA006009FA}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

    Solution

    1. Install the SourceGear Vault client v3.1.9 in “C:\Program Files (x86)\SourceGear\Vault Client”

    2. Backup all files and folders from the folder “C:\Program Files (x86)\SourceGear\Vault Client” to a backup folder “C:\Program Files (x86)\SourceGear\Vault Client Backup”

    3. Uninstall the SourceGear Vault client v3.1.9

    4. Restore all files and folders from the “C:\Program Files (x86)\SourceGear\Vault Client Backup” to the “C:\Program Files (x86)\SourceGear\Vault Client”

    5. Create a FixSourceControlProviderOnWin7x64.reg file and paste the following values:

      Windows Registry Editor Version 5.00
      [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SourceCodeControlProvider]
      "ProviderRegKey"="Software\SourceGear\Vault Client"
      [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SourceCodeControlProvider\InstalledSCCProviders]
      "SourceGear Vault Client"="Software\SourceGear\Vault Client"
      Windows Registry Editor Version 5.00
      [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SourceGear]
      [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SourceGear\Vault Client]
      "SCCServerName"="SourceGear Vault Client"
      "SCCServerPath"="C:\Program Files (x86)\SourceGear\Vault Client\VaultIDE.dll"

    6. Run the FixSourceControlProviderOnWin7x64.reg file.
