I just downloaded Draftsite (free) and tried to run it. The splash screen comes up, then the program window very briefly flashes and disappears. I updated my video drivers and tried again. Same result. I uninstalled and tried the 32 bit version, but it would not install on my Win10 64bit environment. So I reinstalled 64bit. Same result.

My system is an Intel 3rd gen Core i5 with integrated Intel HD4000 graphics running Win10 64bit with latest updates. The software I have which has been known to cause various compatibility issues: Office 365 64bit and Visual Studio 17.

I tried installing on a different computer (8th gen core i5 with Radeon R9 200) and it is working. It asked me to register the software and that all worked. The first computer never got up to asking for registration before crashing.
