FAQ
- What is this?
- IsFlashInstalled.com will tell you if Macromedia/Adobe Flash is installed and what version of Flash is installed on your computer.
- How does it work?
- This site uses three methods to detect the presence of Macromedia/Adobe Flash: JavaScript Flash Detection Library (Flash Detect) (Version 1.0.4), Adobe Flash Player Detection Kit (Revision 1.5) Client-Side Detection (with some customization), and Adobe Flash Player Detection Kit (Revision 1.5) Server-Side Detection (PHP). The PHP script is somewhat unreliable, so it is only used if JavaScript is unavailable.
- Who made this?
- David Newton made the site. The JavaScript Flash Detection Library (Flash Detect) is part of the JavaScript Flash Foundation Series by the JavaScript Flash Foundation Series Group, copyright © 2007 Carl S. Yestrau; the Flash Player Detection Kit is by Adobe.
- Is the code available?
- Yes. The code for the site is available on GitHub, under an MIT license. Fork it, clone it, fix it, etc.

The following issues with server side detection should be closely noted. Internet Explorer on Mac OS is hard-coded to accept '*/*' and cannot be modified dynamically. Secondly, users can manually uninstall Flash Player by deleting the executable itself. This casuses (sic) the custom accept header to be "orphaned" such that server detection logic thinks Flash has been installed, when in fact it is no longer available. It is also possible to disable ActiveX controls through the Windows XP Service Pack 2 security settings, which will similarly cause the custom accept header to be orphaned.
