No AV.

Yes, the guide says to use the Tor Expert Bundle. Which I've installed and reinstalled.

I've not made any changes to tor.config. Doens't even seem to be a file in the Data Directory I extracted..?

I'll try the link you shared, thanks!

I've followed this https://en.bitcoin.it/wiki/Setting_up_a_Tor_hidden_service

Tor Win32 Service is not running.

I've tried this: If you don't see any LISTENING output, it means that Tor service is not working properly and this issue may be related to Windows permissions on the folder you extracted. To fix it go to where you extracted the Tor Expert Bundle and check the top folder Properties > Security > Advanced and verify if in the Permissions tab you have SERVICE with Full Control, if not click Add, click on the link Select a Secure Entity and type SERVICE (all letters in UPPERCASE) then hit enter and select Full Control (Try to start the Tor service again in Windows Services, if it doesn't work, try adding SYSTEM and LOCAL SERVICE with Full Control on folder permissions and repeat the tests above).

Still nothing. Does it matter that the extracted torExpertBundle is in C:\ and the Bitcoin Data Directory is on a HardDrive?

The torrc file says:

Appreciate all help!
