Scripting

Just download their uninstaller and run it with a -uninstall switch, it will run silently.  We just wrap it in a winbatch exe, that also follows with the install of the latest version...They make and uninstaller for 32 and 64 bit.  Easy peasy!

I dont normally use the Utility to uninstall FlashPlayer.

first of all, is FlashPlayer or Flashplayer Plugin are you trying to uninstall? Normally the new version should look after the uninatllation of old version but some time what happens with flash player Not plugin the .ocx file are missing in flash folder and will complain during the uninstall what i normmaly do is deploy a dummy files prior to new deplyment by using a batch file. example below. for 32 bit and also for 64 bit

IF EXIST C:\Windows\SysWOW64\sysprep GOTO Win7

try this but make sure you include all the versions of the .ocx file in your enviorenment.

I also have unisntall script if you needed but try this first.

Disabling Flash's auto-update function should be performed at the packaging/deployment level (depending on how you're deploying). It's documented to death on IT Ninja e.g. here and on Adobe's web site.

1.      Open notepad and save the file as mms.cfg  with following details in the file.

AutoUpdateDisable=1

ProtectedMode=0

2.      Save file then need to be deployed to belowlocation according to architecture type.

64 bit

C:\Windows\SysWOW64\Macromed\Flash\mms.cfg

32 bit

C:\Windows\System32\Macromed\Flash\mms.cfg

Thx Prabs!

The MSI's Upgrade table contains the UpgradeCodes for versions from 6.0.0.0 up to (what I'm calling) the current version, 16.0.0.296. It should just work. If it doesn't, you may have to add the UpgradeCode from whatever MSI installed v15 for you and add it to the MSI you're currently using.

If that MSI doesn't contain an Upgrade table, it's not the official Adobe MSI and you will have to populate the Upgrade table yourself.

The flash installs are MSI files for heavens sake. Just run the following to uninstall any version:

Flash installs are exe I think.
