In some cases you may discover that your installation has become corrupt for several reasons after upgrading the software, including, but not limited to:
| • | Incomplete uninstallation of a previous version | 
| • | Upgrading MetaMiner while its background services were running causing an impartial upgrade | 
| • | Other unknown reasons due to system instability | 
If this happens, we recommend the following sequence of steps:
| 1. | Back up your MetaMiner Database. | 
| 2. | Back up your SQL Script Catalog. To do this, save all .json files found in the directory <METAMINER PROGRAM FOLDER>\Server\scripts to a safe place. | 
| 3. | Redeploy the most current version. | 
| 4. | Uninstall current versions of MetaMiner. | 
| 5. | Clean the program files folders. | 
Initial files of MMS, MMA, and MMC with your system variables are not overwritten during re-installation.
