I have Fireworks CS5 Version 11.0.0.484.
I have Extension Manager CS5.5 Version 5.5.163.
All this on OSX Snow Leopard.
Fireworks isn't listed in Extension Manager.
From within Fireworks, when I go to Commands -> Manage Extensions..., nothing happens.
When I double-click on an MXP file containing a Fireworks extension, I get "This extension cannot be installed, it requires Fireworks version 9 or greater."
What are the troubleshooting steps I should follow?
Your version of the Extension Manager should match the version of the product you are extending. You have to install Extension Manager CS5 to manage extensions for Fireworks CS5. Please go to http://www.adobe.com/exchange/em_download/em50_download.html to download and install Extension Manager CS5.
.
Your Fireworks should have been CS5.1, although the product name is displayed as "Adobe Fireworks CS5" in splash screen and About dialog box. If there is a folder "/Applications/Adobe Fireworks CS5.1" in your machine and you can see "Version 11.1.0.205" in About dialog box, then you have had Fireworks CS5.1, update is unnecessary.
