How to cleanly install Flash Player 20 cleanly with use of msi and vbs script?
In order to maintain updates, we push releases through means of .vbs script and SCCM. With Adobe Flash in particular we uninstall any prior version installed, then the version setup (20 for example) which is pushed silently launches. From the two recent major version releases its been noticed this method doesn't seem to be successful, as Flash Player Active X 19 and 20 fail to remove from Programs and Features rather during the push the additional Flash Player simply installs in addition to the one currently installed resulting in two Adobe Flash Player on one machine.
To uninstall we currently use /maintain activex /uninstall switch which is successful for all versions aside from version 19 and 20. As mentioned, with these it simply leaves the application within Programs and Features. We've tried the Uninstall exe, though are unable to make it silent. And at times it seems a reboot is required.
Is there something further we can do or any other steps we can try when pushing to remove these two versions? Or when using the uninstall .exe is it required to reboot between uninstall and install, and also is there a switch to make it run silently through a .bat or .vbs?
Any suggestions would be much appreciated, thank you!
