Unknown security setting blocked Flash Player installation

A while ago I requested help on the Adobe Flash Player Forum because I couldn't install it.

Unfortunately I didn't receive a response.....I tried to install the latest version yesterday (a different one) - I encountered exactly the same problem as before.

I decided to open the downloads folder, I right clicked on the Flash Player download and selected 'Properties'.

I found this:

"This file came from another computer and might be blocked to help protect this computer"

I clicked on the "Unblock" option beside it and then successfully installed the latest Flash Player.

Where can I find this security setting please so that I can alter it - I don't recall ever setting it up?

XP SP3 / Firefox ESR 38.5.2 / Flash Player Version 20.0.0.306

Security: Avast Antivirus and CryptoPrevent (set to Default, which I believe doesn't affect installations)

No additional settings made on either.

Any help would be much appreciated.

Hi,

This is a setting in your computer, it has nothing to do with Flash Player.  I performed an internet search for "This file came from another computer and might be blocked to help protect this computer" and this got many hits.  A few of the top hits were:

Thank you for your reply. That is the page I have been using......as mentioned above, I have now managed to install the latest Flash Player after 'unblocking' the security setting on my computer that was preventing installation. I have no idea where this security setting is, I need to know so that I can alter it and not have the same problem in future.

I am asking if anyone knows where this security setting can be found.

I've not tried any of these, and can't speak for their effectiveness.  I recommend you perform your own search and experiment with different solutions or go to visit the following Microsoft sites for assistance:  support.microsoft.com answers.microsoft.com

Thank you very much for helping me Maria and taking the time to post those useful links.

Seems there is no easy way to disable this setting, but I will look further into the information you have provided.

I did realise the message was coming from my computer when I opened the download file, only wish I had been notified when I first tried to install / update Flash Player. Had I not later decided to open 'Properties' I would never have seen the "This file came from another computer and might be blocked to help protect this computer" message and known why I couldn't install it!
