I am getting a problem installing this extension into CS6. I just updated a bunch of extensions including this one. When I start DW, I get the normal install routine. Then I get an "ERROR INCOMPLETE INSTALLATION!!!" error. It says that file:///C|Program Files (x86)/Adobe/Adobe Dreamweaver CS6/Configuration/temp/zipphp30/zipphp30_install.xml cannot be found.

I tried removing and reinstalling the extension, but got the same problem.

Then I get errors for parseJson.js not being able to be opened (error 3).

Got this problem with latest purephpupload and the solution is:
close your Dreamweaver, locate your configuration fodler: forums.adobe.com/thread/494812 and rename it to "Configuration1". Restart Dreawmeaver and reinstall the extension.

The problem is that i have to reinstal all my extensions again
