I also have the exact same problem with our HP SIM and VCRM.
HP SIM version is the latest one 7.3.0, VCRM version is also 7.3.0.0.
Today, I installed the latest Hotfix (2014_June) but it did not fix the problem.
HP SIM is running on Windows 2012 R2 English version, and the OS uses "English (United States)" format.
Can anyone give me advice?
