VMware vCenter Server 6.7.x


This issue occurs during upgrades that involve any patched build of vCenter Server on Windows 6.5 to vCenter Server on Windows 6.7.  Legacy service registration entries were not cleared during major upgrades.


This issue is resolved in vCenter Server 6.7 U1, available at VMware Downloads.

To workaround the issue, remove the problematic SCA registration entry.
  1. Created backup of file: scaspec.properties
  • scaspec.properties is located in the C:\Program Files\VMware\vCenter Server\sca\conf directory.
  1. Edit scaspec.properties file.
  2. Remove the entire line referencing the old service ID.
  • The old service ID will be presented during the error message.  It can also be found in the scafirstboot.py_####_stderr.log log.  See symptoms for more details on log locations.
  1. Save the file. 
  2. Upgrade to vCenter Server 6.7.
