Controll Acrobat reader installation from custom Installer

Hi the action that I want to do is Following:

I want to install a progrram that require AcrobatReader MinVersion 9.0. With custom installer I check if exist in destination computer, if not I install it with Pr开发者_开发问答ocess class.

Process.Start(@"c:\File.exe").WaitForExit();

The problem is that in this way I haven't check of installation state.

How can I retrieve this status ?

In practice I want to know if installation done well or not to confirm or unistall my program

Thanking in advance

Piercarlo

You can't have two windows-installer installations running at the same time, so this method will always fail if you're using Windows Installer methods (Adobe uses Windows Installer)
