I downloaded the 15.01.50 installers (32b and 64b). The 64b stopped before 6MB, I deleted it. The 32b came through correctly. I started to install it (by executing the installer tcmd.exe from the last V15 build on the same computer, but cancelled it when I realized I started it unelevated. Several times I tried again. After going through the option screens and selecting "Install", each time "Are you sure you want to cancel Take command 15.01 installation" popped up. Responding "yes" immediately cancelled the installation; "no" restarted the installer at the "Read the JP Software License Terms" page, and eventually arrived at the "cancel" popup, where I am stuck.
