Error installing Insights WBEM providers 10.10

Hi all

We are installing WBEM providers on all our servers in order to monitor them from Microsoft System Center Operations Manager and we have one BL460 where we are having problems installing them. This is the error log (from a reinstall, as it does not appear in installed programs to uninstall it):

I've tried the solutions proposed in this other post, and even tried installing 9.4 with no luck.
