There have been reports of the Gridcoin wallet failing to boot when running from a clean install on version v3.5.9.9. The issues have been traced back to the installer not generating a configuration file for the wallet. A new release to patch this is being worked on right now, but if you want to get your wallet running before the next release here are the steps to generate your own config file:

- Install the Gridcoin wallet as usual. It will fail to boot.

- Navigate to %appdata%/GridcoinResearch

- Add a new text file, open it, and add the following. Note there are three fields you will need to fill out manually.

- Save the file. Ensure that file extensions are visible and then change the name of your text file to 'gridcoinresearch.conf' without the quotes.

You can also generate your own, more advanced, config file using the instructions and explanations available on the [Gridcoin Wiki](http://wiki.gridcoin.us/Gridcoinresearch_config_file). 

This bug does not affect your balance, mining payout, or existing wallet clients in any way. Existing users can safely upgrade their clients to v3.5.9.9.
