When installing Dell EqualLogic SAN HQ 3.10 on a new server, I ran into an issue where the installer looked like it needed to deliver a message about the VC++, but nothing appeared.
I tried installing various versions of the VC++ Redistributable, until I finally hit the right one:
Microsoft Visual C++ 2008 Redistributable – x64 9.0.30729.17
Once this was installed, my installation of SAN HQ proceeded normally.
