Error 5004: Either ACE could not find the specified file or you do not have sufficient rights to access the file

I have reloaded the ADS application as instructed and the responses appear OK. The Eval Expiry date is also OK.

I have created the Database and imported the data from the Paradox original. ( This content is viewable from the Advan Architect and shows OK. )

Within my model Delphi program I place the ADSTable1 component on the form. When I try to set the Database parameter I enter SchoolReg- OK. When I try to set the Tablename Parameter I enter School_roll - OK.

When I try to set the Active parameter to True ( i.e. open the table for the form ) I get the following

Error Message:     ADSTable1: Error 5004: Either ACE could not find the specified file or you do not have sufficient rights to access the file. C:\Program Files ( x86 )\Embarcadero\Rad Studio\12.0\bin\SchoolReg\School-Roll.adt.

The last two elements of this string are actually in E:\Datasets\HeritageADS as expected but the function of the Active parameter above seems to reset this to the wrong path as in the error message.

I feel I must be quite close to having this right. Please can you identify where this wrong path originates?
