I have to do a modification on an old COM+ app written in C#

  • 0

I have to do a modification on an old COM+ app written in C# 2.0. But when I try to register the DLL on a windows server 2008 machine with ‘regsvcs excelserver.dll’, I get the error:

  The following installation error occurred: 
  1: FATAL: Could not find component 'Excelserver.CExcelManager' we just installed

I tried to run in as admin, and turned off UAC, but it doesn’t make a difference.

If I try it on a windows 7 or windows server 2003 machine, it works.

Any ideas why this doesn’t work on a windows server 2008 machine? It seems I don’t find any additional logging in the event log.

Thanks,
L

    You need to register using the 64-bit version of regsvcs instead of the 32-bit version.
