Firebird embedded installation issue: library could not be determined


I've been writing a small Python application that opens a Firebird database.
To achieve this goal I'm using Firebird embedded 2.5.7.27050, 64 bit.

Although, whenever I try to connect to the DB file with Python, I get the following error:

Traceback (most recent call last):
  File "C:\Matteo\CMakeR\initApp.py", line 36, in <module>
    connection = connectToDB(path)
  File "C:\Matteo\CMakeR\initApp.py", line 10, in connectToDB
    charset='WIN1252'
  File "C:\Program Files\Python36\lib\site-packages\fdb\fbcore.py", line 682, in connect
    load_api(fb_library_name)
  File "C:\Program Files\Python36\lib\site-packages\fdb\fbcore.py", line 181, in load_api
    setattr(sys.modules[__name__],'api',fbclient_API(fb_library_name))
  File "C:\Program Files\Python36\lib\site-packages\fdb\ibase.py", line 1398, in __init__
    raise Exception("The location of Firebird Client Library could not be determined.")
Exception: The location of Firebird Client Library could not be determined.
>>> 

It seems that the FB Client is not installed properly.
However I followed very carefully the installation guide inside the doc folder.
Here's my app folder:

Solution

  • Thank you all for helping me solve this issue.
    I finally found a solution thanks to Arioch 'The's suggestion.

    Using Microsoft Process Monitor I was able to detect the folders where my app was looking for the client library. Then I noticed that they were the same folders specified in the PATH environment variable.
    So I added the folder containing my Python file to the PATH variable and everything finally worked out.
