Installing AQT (Technical Notes)


The install process installs AQT for the current user only. If you wish to install AQT for all users on your machine, run the following command:

aqtxxx_setup.exe /V"ALLUSERS=1"

You would either run this from a command prompt, or set this up in a *.bat file.

Allowing a non-administrator user to install AQT

Administrators can set a system policy that allows a non-administrator user to install AQT. This is described in

Install Log

If you are having problems with an install, you can switch on install logging. This is done with the following command:

aqtxxx_setup /V"/l*vx log.txt"

In this example, the log information will be written to file log.txt in the directory where the aqtxxx_setup file is located. This may provide some information to help you understand the problem you are having with the install.

MSI File

When the AQT setup runs, it extracts a MSI (Microsoft Installer) file. This MSI file will be placed in your local AppData directory. For Windows 7 this be:

C:\Users\<user>\AppData\Local\Downloaded Installations

The MSI file can be used to do Repair installs or for Uninstalling AQT.

Strange Problem when running AQT after install

When the install completes, you will be prompted with the Launch the program option. This can sometimes cause a problem.

The install process gains elevated rights, and these will be carried through to AQT when it is runs at the end of the install. AQT will be able to access part of the registry it doesn't normally access. This can result in:

Silent Install

You can do a Silent Install by setting up a script which has the following statement:

aqtxxx_setup.exe /s /v/qn

A Silent Uninstall can be done with:

aqtxxx_setup.exe /s /x /v/qn

What the install does

The install:

No files are written to the Windows system directory. In earlier releases of AQT v9 one dll was loaded into the GAC (Global Assembly Cache) however this is no longer done.

If there are problems with the install, it can be done manually by:

You can back-up your existing install of AQT by copying all the files in the install directory to another location. Note that the AQT executable (aqtv9.exe) cannot run standalone but must have the dlls and other files in the same directory.
