Error code 1605 when installing Adobe Flash Player 11 ActiveX 11.9.900.152

Hi there everyone, this is my first post over here.

I have looked everywhere and can't seem to find a 1605 error code linked with Adobe Flash.

I'm working on a project to fix Adobe Flash installation failures. The current error i'm stuck on is 1605

The installs and uninstalls are already packaged, i only have around 5 failures so far, we have many successful installtions so I know the package isn't corrupt.

Here is the installation log file

I see a differen't product code getting removed on other machines and that's prob because they had a different version of flash installed.
I was however able to install adobe flash versions 11.8 and below successfully, it's just versions 11.9 that fail.

Any advice will be greately appreciated, thanks
