I installed WCS126.96.36.199 on a Win2k3 SP2 Engine for the first time. But as I started the WCS service I got an error.
It seems that the health monitor would not start.
As the WCS188.8.131.52 would not work I installed WCS184.108.40.206 and it works now.
In the install log I found a non fatal error:
Custom Action: com.cisco.packaging.SystemRequirementsCheck
Additional Notes: ERROR - class com.cisco.packaging.SystemRequirementsCheck.install() runtime
Until now I have not found any bug IDs for WCS220.127.116.11.
I use Win2k3 SP2 English with German language and keyboard settings.
