Issue
In PME 7.2.2 and PME 8.x systems, the Windows scheduled tasks that are responsible for executing the database backup/maintenance tasks are not working.
In the Windows Task Scheduler, the tasks appear to completing successfully. Also in checking the Windows Event Viewer, no errors are found from the task executions.
However, when the user follows KB FA263465 to troubleshoot the powershell scripts, the following error is returned:
Could not load file or assembly 'file:///C:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\Microsoft.SqlServer.Management.PSProvider.dll' or one of its dependencies. The system cannot find the file specified.

Environment
Windows Task Scheduler
Windows PowerShell
SQL Server

Cause
The SQL Server PowerShell snapins are not registered.

Resolution
Determine the version of PowerShell that is being executed by the Windows Scheduled Tasks.

- Open the Windows Task Scheduler then open the properties on one of the PME Scheduled Tasks.
- Click on the Actions tab and make note of the directory path.
*For the 64-bit version of PowerShell the directory path will include "system32"
*For the 32-bit version of PowerShell the directory path will include "syswow64"



- Open PowerShell
* Open the (x86) version for 32-bit

- Run the following command to determine if the SQL Server PowerShell Snapins are registered to the appropriate version of PowerShell

get-pssnapin -registered

If the appropriate snapins are registered you will see the following output

Name        : SqlServerCmdletSnapin100
PSVersion   : 2.0
Description : This is a PowerShell snap-in that includes various SQL Server cmdlets.

Name        : SqlServerProviderSnapin100
PSVersion   : 2.0
Description : SQL Server Provider



If the snapins are registered the following procedure will not need to be performed and this is not the cause of the Windows Scheduled tasks failing to execute.

If the snapins are not registered you will receive an error message notifying that no snapins are registered.

- Run the following commands in PowerShell to register the SQL Server PowerShell snapins


For 32-bit PowerShell run:
set-alias installutil $env:windir\microsoft.net\framework\v2.0.50727\installutil

For 64-bit PowerShell run:
set-alias installutil $env:windir\microsoft.net\framework64\v2.0.50727\installutil

For the following commands be sure to check the directory path to ensure that the dll files are in the specified location. The file directory can vary depending on SQL version.

installutil -i "c:\Program Files\Microsoft SQL Server\100\Tools\Binn\Microsoft.SqlServer.Management.PSProvider.dll"

installutil -i "c:\Program Files\Microsoft SQL Server\100\Tools\Binn\Microsoft.SqlServer.Management.PSSnapins.dll"

Add-PSSnapin SqlServerCmdletSnapin100

Add-PSSnapin SqlServerProviderSnapin100


- After these PowerShell commands have been executed run the following command in PowerShell to verify that the SQL Server snapins have been registered.

get-snapin -registered

After the SQL Server PowerShell snapins have been registered, the Windows Scheduled tasks that run the database backup and maintenance tasks will properly execute.
