What is the difference in the way I launch powershell console?

Question

I work with Sharepoint and I need Sharepoint snap-in present in my console host. When I run powershell from my Windows start menu, I run command

Add-PSSnapin Microsoft.Sharepoint.Powershell

snap-in is added ok, and everything works well.

Also, everything is ok, when I run cmd.exe, and type powershell.exe to it and press enter. So I think no shortcut parameters are involved in this problem (but I not 100% sure :) ).

But when I launch powershell through some launcher (I've tested Launchy and Enso) and I try to add the same snap-in, it fails with this error message:

Add-PSSnapin : No snap-ins have been registered for Windows PowerShell version 2.
At somefile.ps1:7 char:14
+     Add-PSSnapin <<<<  Microsoft.Sharepoint.Powershell

[Add-PSSnapin], PSArgumentException
+ FullyQualifiedErrorId :

What is the difference when I launch powershell with launcher?

I think this is not sharepoint related problem but rather powershell one.

(note: I know about Sharepoint management shell and question is not about it)

No sure 100% but you may have a trouble with PowerShell 32 bits versus PowerShell 64 Bits.

For Example if your SnapIn is 64 bits, it can be only use with PowerShell 64 bits. If Launchy and Enso are 32 bits they starts powerShell 32 bits that look for a 32 bits SnapIn. It's the same thing in the other side.

From a 64 bits process, you can force using PowerShell 64 bits using :

c:\windows\system32\WindowsPowerShell\v1.0\powershell.exe

From a 64 bits process, you can force using PowerShell 32 bits using :

c:\windows\syswow64\WindowsPowerShell\v1.0\powershell.exe

From a 32 bits process, you can force using PowerShell 64 bits using (Read this):

c:\windows\sysnative\WindowsPowerShell\v1.0\powershell.exe

Ok, that IS the difference. Thank you. I have both choices when I type powershell - Windows Powershell and Windows Powershell (x86). But powershell is started as 32 bit no matter what version I am trying to run. (Enso is 32bit I guess.) Is this normal behavior? Is there some way to launch 64 bit powershell from 32 bit launcher? – Tight
