Overview:

Can I reinstall Holdem Manager without losing all my settings?  YES

To re-install Holdem Manager without losing all of your settings and preferences, do the following:

Close down Holdem Manager if you haven't already.

Navigate to C:\Program Files\RVG Software\Holdem Manager\Config\

Select all the files and copy them.

Paste them into a folder outside of RVG Software. Remember this location.  (It's best if you place them on your desktop)

Re-install Holdem Manager.

Navigate to where you pasted the files away from the RVG Software folder and copythem.

Paste them back into C:\Program Files\RVG Software\Holdem Manager\Config\. Click on Yes to overwrite the files.

Note: If you just want to keep your HUD settings and not your database username and password or your auto import folders, then you don't need to copy the holdemmanager.config file.
