I'd suggest you to manually remove all you've currently installed (that's causing you trouble) and install them with the individual installers instead of using the integrated installer. Sometimes when the integrated installer has weird behaviors such as the one you describe, the best way to work around it is, as I mentioned, delete everything that's causing problems and install them again manually.
You can find the individual installers in https://software.intel.com/en-us/iot/software/ide.
Let me know if this helps.
