Installing the 64-bit version of IBM Cognos for Microsoft Office
The default installation directory that is used by IBM® Cognos® for Microsoft Office depends on the version that you install. The default paths that are used for the 64-bit installation are different from the default paths that are used in the 32-bit installation.
When you install applications on a x64 (64-bit) Windows system, the program files for 32-bit and 64-bit applications are installed into different directories as follows:
- 64-bit applications are installed to C:\Program Files
- 32-bit applications are installed to C:\Program Files (x86)
- x64 default directory: C:\Program Files\IBM\cognos\Cognos for Microsoft Office
- x86 default directory: C:\Program Files (x86)\IBM\cognos\Cognos for Microsoft Office
- You can run 64-bit and 32-bit Microsoft Office on a 64-bit Microsoft Windows.
- The version of the product that you are installing must match the Microsoft Office version that is installed on the same computer. For example, if you installed 64-bit Office, install the 64-bit version of IBM Cognos for Microsoft Office.
- If you installed 32-bit Office, on a 32-bit or 64-bit Windows, install the 32-bit version of IBM Cognos for Microsoft Office.
- The 64-bit version of IBM Cognos for Microsoft Office does not run on 32-bit Office that is installed on 64-bit Windows.
- If you are an Excel power user working with large amounts of data and need to work with file sizes greater than 2 GB, the 64-bit Office is better able to utilize more memory. If not, use the 32-bit Office 2010 as the default installation on both 32-bit and 64-bit Windows. You will have compatibility with existing 32-bit controls, add-ins, such as IBM Cognos for Microsoft Office, and VBA. 32-bit Office applications on 64-bit Windows are able to open, edit, present documents, and switch among applications faster than on 32-bit Windows.
No special steps are required to install the 32-bit version of IBM Cognos for Microsoft Office in a Microsoft Windows x64 environment. There is support for the 32-bit application to run seamlessly on 64-bit Windows using Windows-32-on-Windows-64 (WOW64). WOW64 is provided with the operating system and you do not have to explicitly enable it. The 64-bit Windows system detects that the program being installed is a 32-bit application and automatically installs it into the WOW64 space.
