Free tools extensions

I downloaded the free tools extensions. I have restarted Dreamweaver cs6, but there are still no signs of the extensions like Google, palletPicker. Also the Insert PayPal Bill Me Later does nothing when clicked. Any help will be appreciated. Thanks

after installing the free tools extension in the extension manager, open dreamweaver, then open a php page to start the WebAssist installer.

after the WebAssist installer completes, makes sure to restart dreamweaver.

if you try using the extension before the webassist installer completes, you may need to uninstall it, then install again.

I tried uninstalling and did what you said. But after it goes through the install. I restarted cs6 and I get this error:
See attachment.
I checked my files, and I do not have the folder WebAssist in my folders where it says should be. I also did a file search, and I do not have the file Shared_Ser_Mactivation.js. I am using Windows XP. Thanks

attached is a copy of the Shared_Ser_Mactivation.js file.

you will need to locate the users configuration folder, see this page for details:

in the users configuration folder place the attached file in Configuration\Shared\WebAssist\Library
