Hello,

take a look here: http://www.appdeploy.com/packages/detail.asp?id=1303

and here: Deploying Adobe Reader 9

The Adobe document says that the version 9 will uninstall all previous versions (I haven't tested it yet, perhaps next week...), but you can check their existence and uninstall them before, s. short example for 8.1.1

@echo off


rem uninstallation of Adobe Reader 8.1.1


set uinstkey=HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall{AC76BA86-7AD7 -1033-7B44-A81100000003}

reg query %uinstkey% /v DisplayVersion | for /F "tokens=1,2,3" %%i in ('findstr /R "REG_SZ"') do echo %%k >%temp%\version.txt 
for /F %%i in ('type %temp%\version.txt') do set Adobeversion=%%i 


if %Adobeversion% == 8.1.1 (


MsiExec.exe /X{AC76BA86-7AD7-1033-7B44-A81100000003}


)

Here are some other script samples (and other stuff) for deinstallation of older versions...: http://www.appdeploy.com/packages/detail.asp?id=915
