Running Quality Window on a 64-bit Operating System

Quality Window is a 32-bit application but runs just fine on Vista, Windows 7 and Windows 8, 64-bit architecture, assuming you are installing from one of our most recent builds (ie QW 5.0 Build 765 or higher).

Quality Window components that would normally be installed in the System32 folder, are now installed in the SysWow64 folder on 64-bit operating systems. Our installer takes care of this for you.

The person installing Quality Window on a workstation should either have administrative rights or at least rights to write entries to the HKLM registry in order to initially set some options as well as to enter the license registration number. For entering license information the first time, go into the Busitech\QW50 folder and right-click on QW.exe and select Run as Administrator – enter license and then exit. The license should now be stored permanently.

For proper operation of Quality Window, the administrator should give write access for the registry tree: HKEY_Local_Machine\Software\Busitech\

Also, they may need appropriate rights to update files in the System32/SysWow64 folders such as QWRules.sys, QWUnits.sys, and QWStats.sys.

Special Note:

Only if you plan to run any Busitech VBS script files on this computer, you must do the following (You may need your system administrator for this):

Edit the following Windows registry key values to start VBScript files with a 32-bit script host:

  1. Change HKEY_CLASSES_ROOT\VBSFile\Shell\Open\Command to %SystemRoot%\SysWOW64\wscript.exe “%1” %*
  2. Change HKEY_CLASSES_ROOT\VBSFile\Shell\Open2\Command to %SystemRoot%\SysWOW64\cscript.exe “%1” %*

Change your file preferences to always run .vbs files with the 32-bit wscript.exe script host:

  1. Right-click a .vbs file and select Open With
  2. In the Open With dialog box, click Browse to locate the 32-bit version of the wscript.exe script host:
  3. C:\WINDOWS\SysWOW64\wscript.exe

Select the Always use the selected program to open this kind of file check box

In other words, change from System32 to SysWow64 in the above instructions. From this point forward, anytime you execute a VBS script file, it will use the 32-bit version of the scripting host instead of the 64-bit.
