I'm using MacOS X and I have Dreamweaver/UltraDev 4 installed as well as Dreameaver MX. How can I install an extension to both applications?

If you have Dreameaver/UltraDev 4 and MX installed in your MacOS computer, then you also have two versions of the Extension Manager installed. The older version supports Dreamweaver/UltraDev 4 run in "Classic" mode and the newer version supports MX natively in the OSX environment.

To install an extension in Dreamweaver 4 or UltraDev 4 on MacOS X:
1) Open the older, pre-MX version of the Extension Manager.
2. Once OS9 in "Classic" mode is loaded and the pre-MX Extension Manager comes up, double click on the .mxp file you wish to install. You can also follow our instructions below on how to set up the OS9 File Exchange so that the .mxp extensions will be recognized in "Classic" mode.

To install an extension in Dreameaver MX on MacOS X:
1) Make sure that no version of the Extension Manager is open.
2) Double-click on the MXP file to install by default into Dreamweaver MX using the newer version of the Extension Manager.
Why doesn't my MacOS recognize the MXP file I just downloaded?
In some cases, we have had reports that MacOS does not recognize the MXP binaries downloaded from the WebAssist.com online store. Common symptoms of this issue are:

1. Double clicking on the MXP does not start up Extension Manager
2. Extension Manager cannot see the MXP file when you try to browse to it even though you can see it using your Finder

If you feel you are experiencing this issue, don't worry! Follow these easy instructions on how to set up your MacOS to recognize MXP files. After you're done with this setup, you can follow the normal installation procedure.

1) Open the File Exchange
The file exchange lets you associate PC file extensions with applications registered with your MacOS (including Extension Manager). You can find the File Exchange from the "Apple" menu under Control Panels (see Figure 1 below). Once you open up the File Exchange (see Figure 2 below), you can scroll down to see if there is a listing for MXP files (the listings are in alphabetical order). You will notice that you don't have an entry for MXP so click the "Add" button to create a new entry. Proceed to step 2 to continue.

2) Add MXP Mapping
Figure 3 shows you the window that is opened when you click the "Add" button in the File Exchange. This screenshot shows the fields already filled out so all you have to do is make sure your addition has the same information. When you're done filling in the information, click the "Add" button and proceed to Step 3 to continue.

3) Finish Mapping and Proceed with installation
Once you've added the mapping for MXP files, you will see an entry for it in the File Exchange (see Figure 4 below). Exit the File Exchange program (don't just close the window) for the changes to take effect. You should now have the ability to double click on MXP files and have Extension Manager open them up or be able to browse to the file from Extension Manager. You can now follow the instructions in our installation guide to complete the process.
