Summary

The following error occurs on Windows 2008 server 64-bit with Internet Information Services (IIS) 7.0:

HTTP 500 - Internal server error

This procedure will enable you to configure IIS to run 32-bit applications on 64-bit windows. Before you do this, note the following:

  • IIS only supports 32-bit worker processes in Worker Process Isolation mode on 64-bit Windows.
  • On 64-bit Windows, the World Wide Web Publishing service can run 32-bit and 64-bit worker processes. Other IIS services like the IIS Admin service, the SMTP service, the NNTP service, and the FTP service run 64-bit processes only.
  • On 64-bit Windows, the World Wide Web Publishing service does not support running 32-bit and 64-bit worker processes concurrently on the same server.

To resolve the issue:

  1. Compare the file size of the VSAPIInfo.dll file from the following folders:
    • ..PCCSRV\WSS\isapi
    • ..PCCSRV\WSS\x64

    If the file size is identical, this means that the 64-bit VSAPIInfo.dll ISAPI module is installed. Otherwise, the 32-bit VSAPIInfo.dll ISAPI module is installed.

  2. Open the IIS Manager.
  3. Click Application Pools.
  4. If you have not yet defined an application pool, do the following:
    1. Click DefaultAppPool.
    2. Click Set Application Pool Defaults.

    Otherwise, select your application pool for Smart Scan Server Virtual Directories.

  5. Under General section, do one of these:
    • If the 32-bit VSAPI Info.dll module is installed, make sure that True is selected.
    • If the 64-bit VSAPI Info.dll module is installed, make sure that False is selected.

  6. Restart IIS.
