After I used RegSupreme - only normal depth - my three applications using dBASE runtime software (BDE and more for dBaseWin 5.7) could not be opened any more. This not being corrected after restore - using the backup made by RegSupreme - I repeated RegSupreme and then re-installed my applications, which then worked again fine. Is there some incompatibility between RegSource and the type of database runtime software I use ? May-be because RegSource itself uses for its execution database software of a similar type but incompatible to 'mine' ?
