We would like to migrate alle Acrobat Reader Installations (Version 5.05 / 5.5 / 6.0) on our Computers to the newest version (7.x). We will deploy the AR7 with GPO.
If i deploy AR7 without an uninstall of the older version, I've got both two versions on these machines.
Is there a way to automatic uninstall AR5 / AR6?

Acrobat Reader 7 will automatically uninstall version 6 during install. The version 5,5 and 5 I'm not sure, havent tried this.
Install 5.5 and 5 on a computer and see if they are uninstalled during installation of v7

Hi eit:

As andler said the new version will automatically remove the old one. For version 5 and 5.5 write a small script in Wise script Editor with the following logic:

1. get the registry key value from registry HKLM\software\microsoft\windows\currentversion\uninstall\<Adobe corresponding package ID>

2. store this value to a variable

3. put an if condition that will check whether the aforementioned key exist or not.

4. in case it exist , the script should then get the value of UninstallString from the same registry hive

5. Execute program that will uninstall this version by parsing the whole uninstallstring.

I hope this would answer your query and sorry for replying late. Too many posts,lol just kiddin.
