I tried installing the LDD on my laptop for school requirements. But, it is not installing. I tried clicking the installer several times but to no avail. At first, it showed an error that it's not installed correctly and whether I liked to reinstall it correctly or not. I chose the former but it just suddenly closed on its own. tried again the latter but it also closed on its own. Then try downloading again the installer. Didn't show an error again but just closes itself. I badly need it for school. What should I do?
