The system administrator has set policies to prevent this installation

While trying to install an msi following prompt appears

ScreenShot486

and the following event is logged in the event log

Event ID – 7000

c:\downloads\filename.msi is not permitted by software restriction policy. The Windows Installer only allows installation of unrestricted items. The authorization level returned by software restriction policy was 0x0 (status return 0x800b010c).

Resolution

This error means that there a revoked certificate your certificate repository from the maker of the software you are trying to install. Once the revoked certificate is deleted, installation would work fine.

To remove the revoked cert follow the instruction below.

Open Internet Explorer, go to Internet Options –> Contents –> Certificates –> Untrusted Publishers –> Remove the publisherScreenShot487

In my case it was Quest Software

ScreenShot489

Close Internet Explorer and try the installer, it should work fine now.

Couldn't find public folder–When Get-PublicFolderStatistics is run in Exchange 2010 SP1

 

When I tried the following cmdlet in EMS

Get-PublicFolder '\PublicfolderName' -Recurse | Get-PublicFolderStatistics

I got the following error

Couldn't find public folder "\PublicfolderName" on server "server.domain.org".
    + CategoryInfo          : InvalidData: (\PublicfolderName:PublicFolderIdParameter) [Get-PublicFolderStatistics], InvalidOperationException
    + FullyQualifiedErrorId : 773CD1AB,Microsoft.Exchange.Management.MapiTasks.GetPublicFolderStatistics

Couldn't find public folder "\PublicFolderName\subfolder" on server "server.domain.org".
    + CategoryInfo          : InvalidData: (\PublicFolderName\subfolder:PublicFolderIdParameter) [Get-PublicFolderStatistics], InvalidOperationException
    + FullyQualifiedErrorId : 773CD1AB,Microsoft.Exchange.Management.MapiTasks.GetPublicFolderStatistics

Solution

This seems to be bug (may be a feature :)

If you add the resultsize parameter to the cmdlet it works fine

Get-PublicFolder '\PublicfolderName' -Recurse | Get-PublicFolderStatistics –ResultSize unlimited
