[Powershell: "An error occurred when loading the system Windows PowerShell Snap-Ins."]

We managed to reproduce this issue and we're working on a fix.

 

Ah, that's good news.  I look forward to it.

I'm not so sure about Powershell being installed. If you run powershell from cmd will it start?

 

Also please run this in powershell and let me know the output:

 

echo ([PSObject].Assembly.Location)

You can also try moving away from PC Monitor's installation folder the System.Management.Automation.dll which will force PC Monitor to use the one in your GAC.

 

If this doesn't fix let me know what operating system type you got (x64 or x86) and what type of installer you used for PC Monitor (x32 or x64).

 

Hope this helps.

 

Powershell is definitely installed, and working correctly.

 

The output of your command: 

 

C:\Windows\assembly\GAC_MSIL\System.Management.Automation\1.0.0.0__31bf3856ad364e35\System.Management.Automation.dll

 

 

Anyway.  I managed to uninstall Powershell 2 which was packaged with Vista (and I said, was working perfectly).

 

I then found that the full Windows Management Framework package would not install; I still receive the "Package not applicable" prompt.

 

So I installed Powershell 1, which is now on my system and working correctly.

 

But I still get the problem.  What's more, I still can't install Powershell 2.  So I've got a downgraded Powershell installation (which includes losing the ISE), and still no joy  Oh well.

I'll try uninstalling the Powershell from the Windows Features, and then manually installing it.  See if that helps.

Try a manual install of powershell on that machine.

 

Yeah, I tried that yesterday, just in case I was missing something.  But if I try to install the standard package of Powershell 2.0, the installer says "This update does not apply to your system," which seems quite sensible, given that Powershell 2 is already installed.

 

I thought about trying Powershell 3, but it's not available for Vista SP2.

 

It seems crazy that this doesn't work just because I'm using the version of Powershell which comes with Vista.

Hey, 

 

Thanks for your reply.

 

Okay, so, firstly I have no C:\Program Files (x86)\Reference Assemblies\Microsoft\WindowsPowerShell directory.  I have C:\Program Files\Reference Assemblies\Microsoft, with only one subdirectory, called Framework, and with no System.Management.Automation.dll to be found at all.

 

There are three copies of System.Management.Automation.dll on my machine, one in the PC Monitor directory, one in a sub-directory of C:\windows\assembly and one in c:\windows\winsxs.

 

Opening up the trace.log file, it contains one line, which is as follows:

 

 

20/12/2012, 22:04:57.212: [service] Received Request Run PowerShell command 'ls' from device Id: 'a4f38f4908c67b6'

 

There are no errors in there at all; I've run several commands to be sure.

Dear All,

 

I'm having some trouble trying to run Windows Powershell commands via PC Monitor (Android App).  When I send any command, I get back the following message:

 

"An error occurred when loading the system Windows PowerShell Snap-Ins.  Please contact Microsoft Support Services."

 

This is displayed in the PowerShell terminal window inside the PC Monitor app.

 

Has anyone seen this problem before?  Or have any ideas how to fix it?

 

I'm running:

- one Windows Vista Home Premium SP2 machine.

- one Windows 7 Starter machine.

 

I get exactly the same error message when attempting to send commands to both machines.  They both have the .NET framework that came with the install, I've not installed any additions, or any new version of PowerShell.  Indeed, the Windows 7 machine is quite new and has few bits of third-party software installed on it.

 

In addition, I run PowerShell scripts from the desktop on both machines without any problems, and with users that are not admins.  I've never seen anything like this message on the desktop.

 

Any help would be greatly appreciated.  Google has turned up a few things, and I've attempted some of the solutions but with no joy.
