Subject Re: [ib-support] Accessing V5 IBDB with old app's TDatabase,Firebird & SQL Links
Author Raymond Kennington

SQL Links installed some really old client files. Reinstalling FB after installing BDE 5.2
has done the job.

My old app (that had over $150 million of data go through for courier bookings and pays
for 300 people) is operational again on WinSE with FB!

Thanks Helen.
