If you are using a version of RapidMiner < 5.0.004 you will have to download and install RapidMiner manually. You can find the download links on our website. The proxy settings were introduced just recently and hence you will have to manually reinstall the new version (5.0.005 is the current one). With the latest versions, you will have proxy settings in the properties dialog of RapidMiner and update should work
- after setting correct proxy settings,
- if you have sufficient access rights to your file system.
Cheers,
