Develop and Download Open Source Software

versions 3.5.5a and below work on my system with no problems, but versions 3.5.6 and above don't work at all. i'm using the zip packages and the problematic versions never open. when i start them, i can see the process in the task manager, but diskinfo's window never shows up and i eventually have to kill it with the task manager. seems like there has been some regression with the 3.5.6 update that remained in the code ever since.
