User-added image


As indicated by this line in the error message "VmEMSetup.Dialogs.VMEMDialog_AddConfig.EnumSSLCertificates()", there is an issue parsing certificates with an empty Subject field, and they will need to be removed. The offending certificates are not self-signed because they are generated from Active Directory Certificate Services.


Remove the certificates that are causing the problem. To do so:

1. First, log onto the Enterprise Manager server and perform the following steps:

·         You will need a small .EXE that will assist with this workaround. Please request the zip file with this .EXE from Support.
·         Download the zip file to the Web Server we are trying to install the Enterprise Manager onto. Once the zip file has been downloaded, extract both files to this directory:
2. Now open the COMMAND PROMPT utility and run this command to execute the .EXE you just extracted: C:\Tools\EnumCert\EnumSSLCertificates.exe
