The easiest way to install qGo on Linux is to get the binary packages from the qGo webpage. Depending on your distribution, that are the rpm or deb packages.
To install the rpm, login as root and type: rpm -i qgo-(version)-1.i386.rpm
On a Debian system, you would do: dpkg -i qgo_(version)-1_i386.deb
To install as shell package, type: sh qgo_(version)-1_i386.sh
You must have installed the most recent version of Qt to make the binaries work reliable.
Installing qGo on Windows is easy.
Download the windows installation package from the qGo webpage: qgo-(version)-win.exe .
Simple double-click on this executable file and the normal windows installation process will start, dialogs will guide you through the installation. qGo will by default be installed in the directory C:\Program Files\qGo\ .
To run qGo, select the link from the start menu.
If you already have qGo installed on your computer, you can download the smaller update package: qgo-(version)-winupdate.exe .
This file is much smaller, as it does not contain the qt library. You can simply install this package over an existing qGo installation, just make sure you choose the same installation directory. The qt library file will stay.
This update package is provided to save people with a slow internet connection some download time.
