behaviour is different between .msi installed and .exe installed flash-player

[informaticien-ldpr]

Hello,

I can watch a difference of behaviour whether FlashPlayer is installed from .msi (via GPO) or from .exe (standalone installation).

(same version 32.0.0.101, of course..)

Some flash based videos cannot appear in Firefox when flashplayer in installed from a .msi

If I unsintall the .msi , and then re-install from .exe, the problem disapears

Same problem about flash videos inlaid in a PDF file.

On a .msi installed computer , inlaid viedo does not appear (and the PDF viewer Adobe-Reader complains about it).

I unsinstall the .msi, and re-install as a .exe

The video becomes visible inside the PDF

Fiew years ago I was facing about the same problem : .msi installations was not detected by firefox (although visible in the windows-list  of installed software), and as a result was uncapable to play some flash-videos.

It seems that 4-5 years later, this problem still remains...

I must handle about 250 computers. Shall I make "hand-made" installation of  the ".exe version" of flash-player on all of the 250 computers ?

best regards

Windows-7 Pro 64b

Firefox : last versions  (63.x) (automatic update actived)

permissions : normal user  (not tested under admin rights, but I believe should be the same)

is it possible to activate de verbose installation when deployment through GPO ?

you should be able to enable it in the registry.  See How do I create an installation log? and scroll down to the "Automated logging with the Windows Installer Logging Policy" section

Here included 2 pictures (screenshot from today  2018-12-21)

- Firefox complains of not finding Flash

- Flash is really installed on the computer

And when asking Firefox to display the list of installed plugins and extensions, flash does not appear.

(meanwhile is does appear in this kind of list on the computer I am using at this moment to write this message)
