Hello avalcarcel,
When installing, it is always better to wait. Only if it seems to be
stuck at the same point for at least 10 minutes, you should make
sure you gather the installation logs before killing any of the
subprocesses.
The installation log should be found in “Documents and Settings\
<username>\Local settings\Temp\”. The name of file will be “Setup Log
<date>.txt”.
The other log files are located in “Documents and Settings/All
Users/NoMachine/var/log”.
Please send logs to issues[at]nomachine[dot]com.
