Hello,

I am trying to share with you, a short tutorial to use PowerShell Custom Action. Please, let me know if there are some mistakes or misunderstanding.

Pre requirement :

• PowerShell v1 or more (in my case i have v2)
• InstallShield v2012 or with powershell module (in my case i have v2012)
• Run MSI file as Admin user

To check the powershell version :

$PSVersionTable  

My custom firt action is write in ps1, remove registry value on installation

Remove-ItemProperty -Path HKLM:\SOFTWARE\Wow6432Node\Citrix\PNAgent -Name ServerURL -ErrorAction SilentlyContinue

and remove files and folders in the folder C:\Windonws\Logs\CBS during uninstallation.

Remove-Item "C:\Windows\Logs\CBS\" -Force -Recurse  -ErrorAction SilentlyContinue  

1)First set a System Search to check PowerShell is installed.

2)Next select the Policy execution for the Custom Action

Have to set the required property .

IS_PS_EXECUTIONPOLICY= Unrestricted|RemoteSigned|AllSigned

I choose Unrestricted because I have not signed my script.

3)After Add the PowerShell Custon Action

4) In the Binary table add the script file

5) Eventually put the custom action in the  sequence between the custom  ISPowerShellStartup  and  ISPowerShellCleanup  with the Condition :

POWERSHELLVERSION<>" " AND REMOVE="ALL" 

6) At the end compile and run it !

For more informations, looking for PowerShell in the InstallShield Help Library.
