In the past, a message similar to what you are seeing could be avoided by opening the application in question, in this case Flash, and opening Extension Manager, then install the extension.

If that doesn't work, then you may have to reinstall Extension Manager, you can find the installers here: http://www.adobe.com/exchange/em_download/

An extension could be for one product only, like Dreamweaver, or it can  be for multiple products, such as Flash and Dreamweaver. I don't recall  seeing any extensions like the later. Could you provide a link to the  extension(s) that your trying to install the give you this message?

If you are installing an extension in Extension Manager and it gives you a message that you need to have Flash 9 or above, then theoretically that means that the extension you are installing has at least some Flash "parts" to it that are supposed to be installed into the Flash application (not the player).

You may want to try to install an extension that is for sure Dreamweaver only. Try this one that one of the Dreamweaver engineers created: http://www.adobe.com/cfusion/exchange/index.cfm?event=extensionDetail& loc=en_us&extid=1739525 I do not have the Flash application installed on the system that I'm writting this one and it installed fine into my Dreamweaver CS5 via the Extension Manager.

Beyond that, since it appears that you bought the extensions, you should contact the extension developers to see if they have any suggestions, as they may have run acorss a similar issue before.

I tried installing "one that one of the Dreamweaver engineers created: http://www.adobe.com/cfusion/exchange/index.cfm?event=extensionDetail& loc=en_us&extid=1739525" into DW CS5 and got the error message "This extension cannot be installed, it requires Dreamweaver version 8 or greater".

Been chasing this for some time reading both Adobe and developer forums to no avail.

I'm having the same problem with DW CS5 and the Extension Manager. I've upgraded DW for years and years now, and the Extension Manager is not recognizing DW CS5. Hopefully Adobe will step in with a clue here???
