AQT is a Windows application, but can be run in Linux.
Both AQT v8 and AQT v9 have different technical environments; AQT v8 is written in Visual Basic V6, AQT v9 was written on Visual Basic .Net.
At this stage, we have only succeeded in running AQT v8 in Linux. For a description of this, see Running AQT v8 under Linux.
For notes on running AQT v9 in Linux, see Running AQT v9 under Linux.
Note that if you are licensed to run AQT v9 you can also run AQT v8.
