    • AMD Turion 64 X2 Mobile Technology and AMD Turion 64 Mobile Technology
    • AMD Athlon 64 for DTR
    • Mobile AMD Athlon 64
    • Mobile AMD Sempron

    To learn AQTime’s limitations that depend on the engaged processor model, see Supported Processor Models.

  • 256MB of RAM (1GB or more recommended).

  • 1.5 GB hard disk space for installation (including 400 MB on the system drive for installing AQTime samples and SDK). 500 MB for using the product.

    AQTime samples and SDK are always installed to the system drive.
  • SVGA (800 × 600) or higher resolution monitor.

  • Mouse or other pointing device.

Note: AQTime may consume a lot of memory to store profiler information. Therefore, when working with large projects, it is recommended that you allocate as much physical RAM as possible so that Windows does not use the swap file.

Operating System and Internet Explorer

  • Operating system:

    • Microsoft Windows 10 (both 32-bit and 64-bit editions).
    • Microsoft Windows 8 and 8.1 (either 32-, or 64-bit edition).
    Profiling of Windows Store (Modern UI) applications is currently not supported.
    • Microsoft Windows Server 2012.
    • Microsoft Windows Server 2008 (either 32-, or 64-bit edition).
      Microsoft Windows Server 2008 R2 is also supported.
    • Microsoft Windows Vista (either 32-, or 64-bit edition).
    • Microsoft Windows Server 2003 (either 32-, or 64-bit edition).
    • Microsoft Windows XP (either 32-, or 64-bit edition).
  • Microsoft Internet Explorer 7.0 or later.

Important notes:
  • If you use a computer that has several processors or a multiple-core processor (for example, dual-core CPU) and has Windows XP Service Pack 2, then you must install the Windows update #896256 in order for AQTime to be able to profile your application correctly. The update can be obtained in the following ways:

  • To use AQTime on Windows Server 2008 R2, the WoW64 component is required. The Server Core installation option for Windows Server 2008 R2 does not install WoW64 by default, so, you should install it yourself. Install the WoW64 component even if you are going to profile 32-bit modules on a 64-bit operating system.

Profiling .NET Applications

To profile .NET applications, Microsoft .NET Framework 1.0, 1.1, 2.0, 3.0, 3.5, 4.0 or 4.5 is required.

Profiling Java Code

To profile Java applications, you must have one of the following Java virtual machines installed on your computer:

  • Sun Java Runtime Environment (JRE) ver. 1.5 - 1.7.

Profiling Silverlight Code

To profile Silverlight applications, you must have Microsoft Silverlight 4 installed on your computer.

Profiling Scripts

To profile VBScript and JScript functions, AQTime requires the Windows Script and Script Debugger components. Typically, these components are already installed on your machine: the Windows Script component is supplied with the operating system (since Windows 98) and the Script Debugger is shipped along with Visual Studio (since version 2003) and Microsoft Office (versions XP and later).

If you have problems with script profiling, try reinstalling these components. You can find standalone packages of these components at Microsoft Download Center ( Search for the following items:

  • Windows Script (Windows Script 5.6 or later is required)
  • Script Debugger

The versions of Windows Script and Script Debugger may be different and incompatible with one another. For information on possible problems and workarounds for them, see Profiling Scripts - Troubleshooting.

To profile script routines, you also need to specify certain user permissions and prepare the host application in a certain way. For detailed information on this, see Profiling Scripts - Prerequisites.

User Permissions

To install and use AQTime, you must have administrator permissions on your computer. AQTime can be installed and used under different user accounts, but all of them must have administrator permissions.

Profiling Under Different User Accounts

AQTime can profile applications under a user account that differs from the current account (the one under which AQTime is running). This can be done only if the current user account has certain user rights in addition to administrator privileges. See Profiling Under Another User Account for details.

AQTime and Windows DDK

If you have Windows DDK installed, then after installing AQTime:

  • Launch Driver Verifier (a tool from the Windows DDK package) and
  • Disable verification of the aqIPD8.sys driver (the aqIPD8.sys driver is part of AQTime).

Driver Verifier blocks the AQTime driver, so you need to disable verification for the AQTime driver.

Integration Into IDEs

AQTime can be integrated into Microsoft Visual Studio and Embarcadero RAD Studio:

  • Microsoft Visual Studio 2017
    Microsoft Visual Studio 2015
    Microsoft Visual Studio 2013
    Microsoft Visual Studio 2012
    Microsoft Visual Studio 2010
    Microsoft Visual Studio 2008
    Microsoft Visual Studio 2005
    Microsoft Visual Studio .NET 2003
    Microsoft Visual Studio .NET

  • Embarcadero RAD Studio 10.4 Sydney
    Embarcadero RAD Studio 10.3 Rio
    Embarcadero RAD Studio 10.2 Tokyo
    Embarcadero RAD Studio 10.1 Berlin
    Embarcadero RAD Studio 10 Seattle
    Embarcadero RAD Studio XE8
    Embarcadero RAD Studio XE7
    Embarcadero RAD Studio XE6

You need to run the IDE as administrator the first time after installing AQTime integration in order to complete the installation.


To activate an AQTime license, the computer must be connected to the Internet. After the license is activated, an Internet connection is not required.

If you are going to use an AQTime Floating User license, your computer must have a network connection.
