I had good success with the [diagnostics.process]::start(&quot;notepad.exe&quot;).WaitForExit() method. 
 
e.g. 
 
# Install Communicator 
[diagnostics.process]::start(&quot;msiexec.exe&quot;,&quot;-i communicator.msi /qb!&quot;).WaitForExit() 
 
# Install Latest Communicator Patch 
[diagnostics.process]::start(&quot;msiexec.exe&quot;,&quot;-p communicator.msp /qb! /norestart&quot;).WaitForExit() 

</div>

I had good success with the [diagnostics.process]::start("notepad.exe").WaitForExit() method.

e.g.

# Install Communicator
[diagnostics.process]::start("msiexec.exe","-i communicator.msi /qb!").WaitForExit()

# Install Latest Communicator Patch
[diagnostics.process]::start("msiexec.exe","-p communicator.msp /qb! /norestart").WaitForExit()

I need to replace a VB script with a Powershell script. The script installs the components for Microsoft Office Communicator. For example, 
 
' Install Communicator 
call WSHShell.Run (&quot;msiexec -i communicator.msi /qb! /norestart&quot;,1,True) 
 
' Install Latest Communicator Patch 
call WSHShell.Run (&quot;msiexec -p communicator.msp /qb! /norestart&quot;,1,True) 
 
I am trying to do the same with Powershell using: 
 
# Install Communicator 
Invoke-Expression -Command &quot;msiexec -i communicator.msi /qb!&quot; 
 
# Install Latest Communicator Patch 
Invoke-Expression -Command &quot;msiexec -p communicator.msp /qb! /norestart&quot; 
 
The trouble is that the second program does not wait for the first program to finish. How can I force each program to wait until the previous program has finished? 
 
Thanks

Run multiple programs from Powershell script

Windows PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and associated scripting language built on the .NET Framework. PowerShell provides full access to the Component Object Model (COM) and Windows Management Instrumentation (WMI), enabling administrators to perform administrative tasks on both local and remote Windows systems as well as WS-Management and Common Information Model (CIM) enabling management of remote Linux systems and network devices.

Powershell

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.
