It's not to hard to get the software running. First get the SDK from the "Downloads" Page. Choose "bundle" folder or just click on this link.
Now unzip it and install with a double click on armsdk_setup_v0.4.exe the software developement kit on your windows machine. Next is to unzip the OpenSourcePilot.zip on a folder somewhere.
Now go to the start menu and start the AscTec SDK. The SDK itself is mainly an Eclipse and you'll see the welcome page:
Choose the workbench option. Now go to the middle of the "Project Explorer" view and choose from the context menu (right mouse click) the "import". Select "Existing Projects into Workspace".
Now browse on the next window to the OpenSourcePilot folder that you expand.
After that you should have a working SDK with the initial sourcecode of the OSP project.
It builds automatically the main.hex file that you can flash to your AscTec Funpilot/OSP. You'll find it in the same folder.
If you want to work with the latest code version of the OSP, simply check out the code from the subversion repository. How to do this with Eclipse you'll find on the following step by step Guide. Check out OSP Code with Eclipse
