To use the Configuration Utility, Microsoft .NET Framework must be installed on the computer. Some versions of the .NET Framework include limitations that can cause the Configuration Utility to take a long time to start. To prevent these problems, the ACUWizard.exe.config file includes this setting:
<runtime>
<generatePublisherEvidence enabled="false"/>
</runtime>
However, not all versions of .NET support this setting.
Solution:
Make sure that the version of .NET Framework installed on the computer supports the generatePublisherEvidence setting.
For example: Version 2.0 (service pack 1) or version 3.0 (service pack 1).
