I think a status update may be helpful. After deleting all other than the one fbclient.dll in myapp folder
1 - Running my app results in the following error message: [FireDAC][Phy][IB]-314. Cannot load vendor library [fbclient.dll]. Hint: check it is in the PATH or application EXE directories, and has x86 bitness. I've checked and it is in both the PATH and app EXE directory. Not at all sure how to check that it has x86 bitness. 2 - IB_SQL gives this new error :( ISC ERROR CODE:335544379 ISC ERROR MESSAGE: unsupported on-disk structure for file D:\my_app\myapp.FDB; found 32779, support 15 3 - FlameRobin IBPP::SQLException Context Database Connect Message =: isc_attach_database failed SQL Message: -902 Unsuccessful execution caused by system error that precludes successful execution of subsequent statements Engine Code :335544721 Engine Message: Unable to complete network request to host "localhost:3050" Failed to establish connection. No connection could be made because the target machine actively refused it.
