Problem when running .ps1 script from external program

Question

I'm trying to run simple Powershell script (eg. just with dir command) on Windows Server 2008 using external program which will call Powershell

powershell.exe "& 'C:\Temp\myscript.ps1'"

I have set (run as administrator) execution-policy unrestricted. After all, I get this error from the client

99: File C:\Temp\myscript.ps1 cannot be loaded because the execution of scripts is disabled on this system. Please
 see "get-help about_signing" for more detai  ls.  At line:1 char:2  + & <<<<  'C:\Temp\myscript.ps1'      + CategoryInfo
: NotSpecified: (:) [], PSSecurityException      + FullyQualifiedErrorId : RuntimeException

Why I'm getting this error? Isn't unrestricted execution policy enough?

Problem solved: There is two Powershell's in Windows Server 2008, x64 and x86. I had to set execution policy unrestricted in both of them. — jjoras

Or

You can use -ExecutionPolicy parameter of PowerShell.exe to set the execution policy to unrestricted only for that session. This helps in keeping the system wide policy to deafult.
