The download of Adobe Flash v27 for Firefox on Windows 10 fails when I try to run it. If I 'run as administrator' I do get a dialogue box requesting authority to make changes to the computer, but then nothing. Therwise (eg if I double-click on the file) there is a small amount of computer activity but nothing actually happens.
Any suggestions please?
I was not able to reproduce the issue. Could you please try uninstalling Flash player from Uninstall Flash Player for Windows and try downloading/installing again.
If the problem persists, please let us know.
Is this a machine in an enterprise organization? It's quite possible for a system administrator to push Group Security Policies that would prevent our installers from running.
The installation logs would be pretty helpful in understanding why the installation is failing:
Also, you might try the alternate "offline" installers. Links are at the bottom of the guide.
