you can use the services api to retrive the engine
for example using uib or ibo you can retrieve
InfoImplementation
this is the logic in Lazarus for example
Label1.caption:= inttostr(UIBDataBase1.InfoImplementation);
and then
make use the implementation number to get the text and 64 bitness
in the source code for firebird 2.5 in src/jrd/utl.cpp is defined this way

"Firebird/linux AMD64", // 66
"Firebird/FreeBSD/amd64", // 67
"Firebird/x86-64/Windows NT", // 68


so if is 68 or 66 then is 64 bit/x64-64
