Adobe Flash won't install properly

The browsers I use are Mozilla Nightly and Comodo Dragon, and it seems like the Adobe Flash installer is having trouble distinguishing between the two.

I recently noticed that for some reason, YouTube videos and other Flash applications did not work in Dragon anymore, while I remember to have them work before. Dragon notified me of a plugin missing, so I tried installing Adobe Flash by going to and installed it using the autodetected settings, ‘Windows 64-bit , English, Chrome’, but when I ran the installer, it urged me to close Nightly (I had it open at the time) halfway through the process. I did so, and exited the installer when it was done. However, nothing was installed on Dragon yet, as I didn’t see any plugin with a/the name (similar to) ‘(Adobe) Flash’. I tried rerunning the installer without closing Nightly and just telling it to retry, but it would just repeat the prompt.

After that, I went to the Adobe Flash page again and clicked ‘Do you have a different operating system or browser?’, which as expected didn’t have specific support for Dragon, so I just picked ‘Windows 7 64-bits, English, Other Browsers’. I reran the steps I took with the previous installer, but it still didn’t work.

Additional info:

  • Mozilla Nightly has the last version of Adobe Flash.
  • I use a Windows 7 64-bits system.
  • If I’m right, Flash has worked on Dragon in the past. Not sure though.

Does anyone know how to fix this?
Thanks in advance,

Flash Player (64 bit) works fine in Dragon 18.3 (and Nightly/Firefox 15.0a1) on Windows 7 64-bit when I test.

You can download it here (“Plugin-based browsers”):

Close Dragon and other plugin-based browsers before installing Flash Player.

Type/paste dragon://plugins in Dragon’s address-bar, to see if Flash is enabled.

It worked, thanks! It still prompted me to close Nightly, so I just closed both, and it installed properly, as it now properly views Flash applications.

You’re welcome. Glad it worked. :slight_smile: And, yes, as all plugin-based browsers use the same Flash Player, they all have to be closed when installing it.
