Python Firebird WinError 193 connection error

import fdb

def main():
    con = fdb.connect(dsn='C:\AKINSOFT\Wolvox8\Database_FB\SIRKET.FDB', user='sysdba', password='masterkey')

if __name__ == '__main__':
    main()

I wrote a simple code for connecting a Firebird database with Python and fdb. When I run this, I get an winerror 193

Traceback (most recent call last):

>Solution :

The English error is "[WinError 193] %1 is not a valid Win32 application", and it means you’re trying to load a 32-bit DLL in a 64-bit process (or a 64-bit DLL in a 32-bit process). This means that you don’t have a valid fbclient.dll on the PATH that matches the bitness of your Python process, but do have one of the wrong bitness.

So, find out if you’re using a 32-bit or 64-bit Python (likely 64-bit these days), and use a Firebird installer of the appropriate bitness to install the client library.

If you don’t have or don’t want fbclient.dll on the PATH, you can also use fdb.load_api(..) or the fb_library_name connection property to specify the path to a fbclient.dll of the appropriate bitness.

As an aside, fdb has been superseded by the firebird-driver library.
