Summary
In Web Access 8.2 and later, the installation contains both a 32-bit and 64-bit version of Web Access. Depending on the architecture of the operating system, the installation process automatically installs the version corresponding to your version of Windows. On the 64-bit versions of Windows Server 2003 and Windows XP, this can cause compatibility issues because IIS 6.0 does not support running 32-bit and 64-bit worker processes concurrently.
See the following scenario:
Resolution
Manually launch the Web Access installation's setup.exe with the following command-line parameter:
/force32bit
The installation process will install the 32-bit version of Web Access.
"C:\temp\Web Access 8.3.1\en-US\WebAccess\Install\setup.exe" /force32bit
Replace "C:\temp\Web Access 8.3.1" with the actual location of the installation package.
