My problem seems a bit different than the one others have noted: Mine doesn't just disappear, it throws up the error reporting window
My system is Windows 10 Version 1709 build 16299.371
I have had Cura 3.2.1 running just fine (installed on drive E, in a remote programs folder) and downloaded the 3.3 installer to check out. The 3.3 Installer correctly saw that I had 3.2 installed and offerd to uninstall it, I'm glad I chose to keep 3.2.1, because 3.3 crashes on startup every time. I installed 3.3 to the same remote programs folder as 3.2.1 was installed in and the crash report I get is attached. This seems like a very nonsensical error to me...
