You receive an "Error registering COM+ application" error message when you install an application proxy in COM+ 1.0 (873192)


The information in this article applies to:

  • Microsoft COM+ 1.5, when used with:
    • the operating system: Microsoft Windows Server 2003
    • the operating system: Microsoft Windows XP
  • Microsoft COM+ 1.0, when used with:

SYMPTOMS

When you export an application proxy from Microsoft COM+ 1.5, and then you try to install the application proxy in COM+ 1.0, you receive the following error message:
Error registering COM+ Application. Contact your
support personnel for more information.
Note Microsoft Windows Server 2003 and Windows XP run COM+ 1.5, and Windows 2000 runs COM+ 1.0.

CAUSE

This problem occurs because the versions of COM+ do not match. The Save application in COM+ 1.0 format - some properties may be lost option on the Application Export Information page must be enabled if you want to export your application proxy for COM+ 1.0. If you try to export the application proxy without enabling this option, the application proxy is exported only for COM+ 1.5 for Windows XP or for Windows Server 2003. Therefore, you receive the error message when you install the application proxy on computers that run COM+ 1.0.

  1. Click Start, click Run, type Installation drive:\WINDOWS\system32\Com\comexp.msc (where Installation drive is the disk drive where your operating system is installed), and then click OK.
  2. Expand Component Services, expand Computers, and then expand My Computer.
  3. Expand COM+ Applications, and then locate the COM+ application that you want to export.
  4. Right-click the COM+ application, and then click Export.
  5. On the Welcome to the COM+ Application Export Wizard page, click Next.

  8. Click to select the Save application in COM+ 1.0 format - some properties may be lost check box to export the application for COM+ 1.0.
