If you do not have the X$Attrib system table defined on your system, the Admin component will not be able to manage your tables.
The solution is to use an alternate admin config file (pervasive_adm2.cfg) that does not refer to the X$Attrib table. Some attributes of your tables (Default and Case Sensitivity) will not be displayed.
To use this alternate cfg file, go to Options > Config Files. Find the entry for Pervasive and change the Admin Cfg value to pervasive_adm2
This change may also be required if you are running Pervasive.SQL v7, which can misreport column types.
