We have created a mini web program for running PowerShell in asp.net. the PowerShell command is running fine. but when we try to import the MSOnline module, it will be shown the following error:
Could not load file or assembly 'file:///C:\Windows\system32\WindowsPowerShell\v1.0\Modules\MSOnline\Microsoft.Online.Administration.Automation.PSModule.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.
Dim Ps As PowerShell = PowerShell.Create()
