Do I have to write "D:\Blockchain" or "D:\Blockchain\blocks"?
I believe
D:\Blockchain\blocks would be correct. Sorry for confusing you.
Do I have to put this file into the directory of Armory or into the corresponding AppData folder from Windows?
It needs to be placed into the Armory data directory. Usually this is in your AppData directory.
The standard path is:
C:\Users\USERNAME\AppData\Roaming\ArmoryYou can access it by pressing
WIN-key and
R, then entering:
~/ArmoryThe config file is called
armoryqt.confIs it neccessary not having Bitcoin Core running while Armory runs?
Core needs to be running and fully synced for armory to function properly.
But if you don't want to send your funds (or don't want to have armory in online mode), core does not need to be running.
If it still doesn't work, upload the log files to
pastebin and provide us the links.
The log files can be found in the data directory of armory (named:
armorylog and
dblog).
