    You need to install Lower version of SDK(v 1.4.2_08) I am using this with no problem. I don't think anything higer is recommended by SAP.

      I got this solution from SAP and it worked.

      This is a known problem that appers due to an implementation bug,

      while trying to read the proxy information. The studio expects non-

      empty value for key com.tssap.config/proxy, located in


      ugin_customization.ini file. During the installation no value is

      assigned to this key (as you mentioned - no proxy in your case). The

      problem will be fixed for SP14, however there is a workaround:

      1. Change the value for key com.tssap.config/proxy in

      plugin_customization.ini to something like this - proxy:80.

      2. After this change the DevStudio should start and you'll be able to

      configure your proxy settings from Menu Window->Preferences-

      >Workbench->Proxy Settings. (In your case - disable the proxy
