So what version are you running now? If it's not 17.04.02, getting that installed should be your first goal. Try downloading the running the full installer Dave posted
to your system, then right click on the exe file and Run As Administrator and see if that will work for you. If it does not, try uninstalling your existing copy of 17, reboot and then right click on the downloaded full installer again and run as administrator. One of these methods should work unless you have an anti virus or malware app blocking something. I would bet once you get the version up to 17.04.02 your issues will be fixed.
You could test your current install by opening a new default drawing and adding about 15 layers and then use the Layer, F1 On/Off keystorke to see if it crashes.
