Thank you for interest in the Intel® Edison Breakout Board.
As you probably know, what you find in the Intel System Studio IoT Edition is an Eclipse-based IDE. So anything related to Eclipse and the complementary IoT projects is available here https://www.eclipse.org/ and here https://iot.eclipse.org/.
But you should keep in mind that, since those are not the Edison-recommended versions (the one in System Studio IoT version is the supported version), some issues may or may not arise. What I can recommend is to upgrade your OS (Windows 8 or later), so you can get the adequate support.
Unfortunately, since your OS is no longer supported, there is not a way to upgrade your current version through System Studio IoT Edition.
I'll be waiting for your response.
