    Uninstalling package

    I have had a problem with the Multiple Uploader working on one of our sites and so I am trying to uninstall it so that I can start a fresh, however when I try to follow the instructions to remove the Multiple File Upload property from the folder Media Type I get the following error:

    Server Error in '/' Application.

    Object reference not set to an instance of an object.

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Alternatively, if anyone can help with the original error we have experienced that means I do not need to remove the property then that would be good.  Basically, when I click on a folder I get the following error:

    Server Error in '/' Application.

    The given key was not present in the dictionary.

    Any help would be appreciated.

    I too am getting the error:

    The given key was not present in the dictionary.

    Any thoughts, please help...

    As further info: Umbraco 4.0.3 which has been a entire copied umbraco instance with new db and many mods made, and in final checking have found this error meaning that Multiple File Upload won't work, and i cant reinstall it either, installation gives the same error.... arrrgh!

    Just wanted to see if anyone had any luck resolving this error if they have had it occur?

    Did you removed the datatype from the document type properties or media type properties before uninstalling the "data type" package?  Generally a good practice to avoid problems.  It also would not hurt to recycle the app_pool after uninstall of the package to clear any references.

    Ugh. I forgot to remove the datatype from the "Folder" Media Type before uninstalling, and now I can't edit the "Folder" type and get an error when clicking on any Folder in the media section.

    I don't have access to this website's database nor the iis server...

    Anyone have any good ideas how I can remove this from my Folder Media Type?

    Thanks

    I have the same issue. The multiple file uploader didn't install property on a 4.7.1 installation and it won't uninstall. And also now can't view the package repository, gives a 500 error:( 

    Any clues to save the site would be appreciated.

    Recyling the appPool did the trick!  Then manually uninstalled as per the documentation.
