Set up your TeX environment
TeX64 checks for a usable TeX installation before you build.
Use an existing installation
When a working TeX distribution is already installed, TeX64 uses it without changing it.
Choose Quick setup when TeX is missing
Quick setup installs TeX64’s lightweight managed environment without administrator access. Missing packages are added when a document needs them.
Expand only when you need every package
From Settings, a lightweight TeX64 environment can be expanded to the full TeX Live package set.
