  • Helm 4


After installing Microsoft .NET Framework 3.5 Family Update (KB951847)
Parallels Helm stop working at all. Helm configuration tool does not
work as well.


Parallels Helm 4.1, Parallels Helm 4.0


The version of code protector (CLISecure) used for 4.1.0 and 4.0
versions of Parallels Helm is not compatible with KB951847 Microsoft


If you have old version of Helm 4.0 (older than 4.0.20),  please download latest HelmConfigurationTool.exe version 4.0.20 (see in attachments) Copy/replace it to ...\Helm4\Tools folder.

Launch the Helm_KB951847_Patch.exe command line tool on the affected server. This tool will fix the problem. It produces log file  (Helm_KB951847_Patch.log) which can be used to track patch process. If after this procedure Parallels Helm still does not work, launch  Configuration Tool (it should work) and perform Helm update.

Warning: Helm_KB951847_Patch.exe restart IIS
