Fix broken Adobe Flash Player 10 ActiveX Installs, Fully Remove Flash 10
Check out this registry key for the packaged GUID, (note yours will be different, I think this was from Flash v10.2) you will have to search for the ProductName string value under each one. HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\E2B30D5E4D2BF7746AD0E891968D12AF Look for the line below in the key you have just found, here is the GUID for Flash contained in it. (Note its actually the same thing encoded, see below to decode it) C:\WINDOWS\Installer\{E5D03B2E-B2D4-477F-A60D-8E1969D821FA}\ARPPRODUCTICON.exe You can then try a normal remove (with a log if you wish, otherwise omit the /Li ending bit) followed by an msizap msiexec /x {E5D03B2E-B2D4-477F-A60D-8E1969D821FA} /qn /Li "c:\temp\flashlog.txt" msizap TWAP {E5D03B2E-B2D4-477F-A60D-8E1969D821FA}

You should see HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\xxxxxxxxxxxxxxxxxxxxxx has now gone amongst other things.

Then remove the Flash folder. C:\Windows\system32\Macromed\Flash

If you are using Windows AD pushed out system (Mandatory software) to deploy it, you will also need to remove the following key to get it reinstalled. (You will need to search through AppMgmt keys to find the right one, note the GUID isnt related here. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Group Policy\AppMgmt\{xxxxxxxxxxxxxxxxxxxxx}, Deployment Name, Adobe Flash blah blah
