I'm trying to update games with HLDSUpdateTool through both TCAdmin and just the regular run command - and it always hangs at Updating Installation. Has never done this in the past and I don't know why it is now. Any certain ports to open? Any information is appreciated.

Three things to check


1. If running via command make sure hlsupdatetool is in the location you are updating from



dir D:\GameInstalls\gmod10


2. if its being run by tcadmin it should be put in your monitor folder

3. Try adding the exe to your firewall

Thanks for the suggestions louise. All of those are covered.


I am having the same problem that tehrichie had. The updater hangs at Updating Installation, whether it is started manually or from TCAdmin. However, it is able to download a new installation without any fuss.

There is a new issue with this now as of the latest release


try updating your servers i currently get


CMultiFieldBlob: Unable to grow blob




CMultiFieldBlob: Unable to grow blob


its a valve issue


even trying to add fresh files at a different location the error will still come up
