Having problems updating rapidminer 5.  Sorry, I should have posted it here rather than in the other forum.  (I'm new here)

When i try to update, it gives me the following error:

"Error installing update: .\lib\plugins\managed\rmx_weka-5.0.0.jar (The system cannot find the path specified)  Reason: .\lib\plugins\managed\rmx_weka-5.0.0.jar (The system cannot find the path specified"

This happens with the Weka, parallel processing, text processing, and other extensions.

please help!!  Thanks everyone!

    Installation and Update of RapidMiner 5 Extensions under Windows 7 (and Windows Vista):

    Microsoft Windows 7 by default starts all applications with limited access rights.  This also applies to RapidMiner 5, which hence is not allowed to write into its own program directory.  Since RapidMiner 5 needs to be able to write into its own program directory in order to install and later update plugins, RapidMiner 5 needs to be started with administrator access rights, if you would like to install or update RapidMiner 5 extensions.  The same applies to updates of the RapidMiner core.  This is not a bug of RapidMiner, but a result of how Windows 7 treats the access rights of its applications.  The problem can be by-passed as follows:

    Installation and Update of RapidMiner 5 Extensions under Windows 7 (and Windows Vista):
       
    • Start RapidMiner 5 not via double click on its icon as usually, but by selecting the RapidMiner 5 icon with the computer mouse, holding the right mouse button pressed, and then selecting “Run with administrator rights” in the context menu.
    •  
    • After starting RapidMiner 5 with administrator rights, go to its “Help” menu, choose “Update RapidMiner”, select the desired RapidMiner 5 extensions, and then press the “Install” button.
    •  
    • For the update or installation to become effective, you first need to restart RapidMiner.  This second start-up also has to be done in the same way with administrator rights, because the actual installation of the extensions happens at the next start-up of the program after the download of the extensions or updates.
    •  
    • Later program starts of RapidMiner 5 can be performed the usual way, i.e. via double clicking the RapidMiner icon, via the Windows start menu, via a RapidMiner start script, or via the context menu like above.  All these ways work, both, with administrator rights as well as without.  The design and execution of RapidMiner data mining processes usually does not require administrator rights.  Only whenever you would like to install or update RapidMiner or some of its extensions, the above procedure for the start-up with administrator rights needs to be repeated.
    Without administrator rights, RapidMiner 5 cannot install or update its extensions, because it needs be able to write these extensions into its program director.  The next version of RapidMiner will provide a more informative help message instead of the current error message in case a RapidMiner update or extension is attempted without administrator rights.
