Install on 64-bit Windows operating systems

 

Release 6.0.2.1 includes support for 32-bit applications running on 64-bit operating systems, these operating systems are detailed in Operating systems.

Before installing WebSphere MQ V6.0.2.1 on an x64 version operating system, install Microsoft Visual Studio 2005. Language specific versions of vcredist_x64.exe are included in the downloadable zip file for version 6.0.2.1.

If, during installation on a 64-bit operating system, the correct Microsoft Visual 2005 files are not detected, message AMQ4765 is displayed reading:

Ensure the prerequisite 'Microsoft Visual C++ 2005 Redistributable Package (x64)' is installed before continuing installation of the this fax pack.

You do not need to cancel the fix pack installation if this message is produced. After running vcredist_x64.exe select Retry on the message box to continue the fixpack installation.

When running a silent fixpack installation, no message box is displayed if the correct level of Microsoft Visual C++ 2005 cannot be detected. Instead, the fixpack installation fails and an entry is written into the fixpack log file detailing the problem. To automate the fixpack installation silently, Microsoft Visual C++ 2005 can also be silently installed prior to installing the WebSphere MQ V6.0.2.1 fixpack using vcredist_x64.exe /Q option.

Otherwise, there are no 64-bit specific actions that need to be performed to install and use WebSphere MQ on a 64-bit Windows system.

 

Install directory used for 64-bit Windows operating systems

On 64-bit Windows, the default installation location is C:\Program Files (x86)\IBM\WebSphere MQ as opposed to C:\Program Files\IBM\WebSphere MQ. Even if you explicitly set the installation program to install WebSphere MQ in C:\\IBM\WebSphere MQ it will get installed in C:\ (x86)\IBM\WebSphere MQ.

Wherever the default installation location occurs in the documentation or C:\\IBM\WebSphere MQ is specifically documented, for 64-bit operating systems the file path should be read C:\ (x86)\IBM\WebSphere MQ.

 

.NET applications on 64-bit operating systems

The 32-bit version of the .NET framework versions 1.1 and 2.0 are both supported for use with Windows 64-bit operating systems. One of these versions must be installed if you wish to write .NET applications.

By default, applications built using .NET Framework 2.0 can run as either 32-bit or 64-bit depending on your operating system. However, because WebSphere MQ supports 32-bit applications only, if you are using a 64-bit operating system, applications must be built with the platform explicitly set to x86, so that they will run as 32-bit applications on 64-bit Windows.
