[DUG] ClientDataset and Key Violation

[Gary T. Benner]

[Reply]

HI Rohit,

It depends where the registered version is located...... in the application directory, or /windows/system32 ....  rebooting doesn't change that.

Try manually re-registering  ( using regsrv32.exe ) the latest version of midas.dll just in case ... ( to be sure that windows has the right location registered )

cheers

Gary
