If your MacBook does not boot, then you can't remove those apps. It's as simple as that.
Contact the customer support for those programs and explain to them that logging out will not be possible.
If they refuse to assist in some way then I would find other software to use for those tasks.
Have you taken the MacBook to Apple or an Apple service provider for repair estimation?
You can make a Genius Bar appointment for hardware/software service and support using this link:
