I keep getting this error:
EXCEPTION: N5boost16exception_detail10clone_implINS0_19error_info_injectorINS_15
program_options26invalid_config_file_syntaxEEEEE
the options configuration file contains an invalid line 'XXXXXXXXXXX'
Where can I find the bitcoin.conf file?
The default location of bitcoin.conf depends on your operating system:
| OS | Path |
|---|---|
| Windows XP | C:\Documents and Settings\<username>\Application Data\Bitcoin\bitcoin.conf |
| Windows Vista, 7, 10 | C:\Users\<username>\AppData\Roaming\Bitcoin |
| Linux | /home/<username>/.bitcoin/bitcoin.conf |
| Mac OSX | /Users/<username>/Library/Application Support/Bitcoin/bitcoin.conf |
Not directly related to this question, but if you cannot find the configuration file at the above path: note that the configuration file is not necessary to run Bitcoin-Qt. If it is not yet present, you can simply create it with any text editor.
Note that for Windows the location of the configuration folder where bitcoin.conf is located is saved in the registry.
Its default path is indeed C:\Users\<username>\AppData\Roaming\Bitcoin but if that location was changed then in order to find the current folder you will have to look in HKEY_CURRENT_USER\Software\Bitcoin\Bitcoin-Qt at the REG_SZ strDataDir.
I would guess that that refers to your bitcoin.conf. There's platform-specific information on where to find it at: https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File
In bitcoin-core version 0.14.2, it looks for it in the data-dir folder https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File
The bitcoin.conf file is not created by default, you will need to create it yourself.
And also, I never had a c:\users\[username]\appdata\roaming\bitcoin folder as many online answers will suggest, this is because when I installed the bitcoin core program, I chose to put my data directory in a different place than default.
