If you are attempting a silent installation of Maple, but it hangs, you likely need to bypass the font installation using the installfonts option:
Maple2020.0WindowsX64Installer.exe --installfonts 0 --optionfile installer.properties
If this is the first version of Maple to be installed, you will then need to install the fonts separately from this package.
If MapleSim installation hangs due to the .Net framework already being installed you should include the option --disable-components CadToolbox
MapleSim2020.1ProductWindowsX64Installer.exe --mode unattended --maplepath "C:/Program Files/Maple 2019" --disable-components CadToolbox --optionfile installer.properties
