I recently extracted an Acrobat Reader install exe file by starting the exe file and before hitting continue I went to Start and run and typeed '%ProgramData%\Adobe\Setup' and hit OK.
From there I was able to edit the MSI file in Adobe Customization wizard. I did this so i could silently install, stop auto-updates, and stop reboot prompt upon installation in a powershell 2.0 script.
How do i do this same MSI extraction process for Flash Player 13?

In this case, the MSI is available for download from Adobe, and is probably a better solution.
