If you were on about the tcadmin version, it depends on your OS, if the server you're trying to install to has a faulty steamcmd install on a windows box, it should be in:
NB: My master server is Linux, so I'm a bit more knowledgeable but I do have a Windows server too;
C:\Program Files\TCAdmin2\Monitor\Tools
Simply delete the steamcmd folder, create/update a new gameserver and it should extract/create a fresh steamcmd copy, if this doesn't work then something is wrong on your end, disabling the ie protection like Dennis said would be a good idea, if you need any help on this I may be able to investigate further for you, or you could always send a ticket to tcadmin support.
Kind Regards,
