Debug Logging
**Messenger**
Messenger for Windows has the ability to create a log file.
Here is a reg file [Debug.reg](https://storage.levelleap.com/nina/protocols/msnp/development/Debug.reg) to enable the logging on (at least) versions < 9.
The log file will be in the `Documents > My Received Files` (the folder name depends on Messenger language).
In Windows Live Messenger, you will find some logs there: `C:\Users\{user}\AppData\Local\Microsoft\Messenger\`
**Microsoft Identity Control**
You can use these 2 reg files to turn on/off logging for microsoft identity control components (msidcrl, ...):
[Enable_Logging.reg](https://storage.levelleap.com/nina/protocols/msnp/development/Enable_Logging.reg)
[Disable_Logging.reg](https://storage.levelleap.com/nina/protocols/msnp/development/Disable_Logging.reg)
The path were the log will be is in the reg file.
If you don't change the path in the reg files, you need to create 2 folders: `C:\MSOTrace` and `C:\MSOTraceLite`
**Sources**
NOTE: Please replace `MSOIdentityCRL` by `IdentityCRL` in registry keys name when needed.
