I know its been a while but im posting for anyone who needs help in the future.
If you are trying to reinstall STO, but you try to enter your key again and it says that it is already active, don't sweat.
If you already own the game and it was accidentaly (or purposly) uninstalled, you can still install it again.
When the product activation key screen comes up, just exit out of it. Your game will continue to install just fine.
Important
Although it may seem to get hung up, it isn't. When it gets to the part where it is trying to execute a program that ends in "/SILENT", it is just waiting for the key to be entered. It will continue on the installation if you just exit out of the key activation screen.
You also may think that it is getting hung up on the .hogg files. It isn't. As stated earlier in this forum by Kineel, .hogg files are massive bianary files that can take many minutes to install. I have a pretty new (7 months) computer and it took me 15 minutes to get through the .hogg files.
I hope this cleared up any confusion
(Dont try to hack the game like this, just buy it, its worth every penny:D)

You can't do it anyway, the servers won't let you in without a valid key.
