If you have Delphi 2.0 then you have to install our library from the directory \lib_2.0\ (The dcu files was compiled by Delphi 2.17.53).
if you have Delphi 2.01 then you have to install our library from the directory \lib_2.1\ (The dcu files was compiled by Delphi 2.17.69.0)  

To determinate what's version you are have, go to Delphi About Dialog Form and press ALT + VERSION. If the name of the version is less than 2.17.60 - it's Delphi 2.0, otherwise it's Delphi 2.01.

If you try to install  the wrong version for your Delphi, the error:
'The unit autoreg was compiled was wrong version of the dbgrids.pas' or
'The unit adbgrid was compiled was wrong version of the dbgrids.pas' will be appear.

Be careful. 

You will haven't any problem with registered version (You will have the sources). 

Good Luck !!!
