[Errno 22] Invalid argument when reading a mdf file about mdfreader HOT 4 CLOSED

From the traceback, it seems pointer to a comment in your header file is not correct. This ispretty basic stuff, I do not really see why there is problem, first time so far.
Which software generated these files ?
I see two approaches to support you :

1. you download mdfvalidator from vector site and confirm health of your file
2. you send me your file if there no confidentiality issue and I can troubleshoot

from mdfreader.

Unfortunately I have no information regarding the original software.

1. Also I am on a unix system and therefore cannot install mdfvalidator or any other basic tools that can handle mdf files. This is the reason why I'd like to convert the file.
2. I cannot send you my mdf file, however I also tried with the two mdf files from this thread http://www.telerik.com/forums/where-to-download-northwind-mdf-and-telerik-mdf and got the same result.

Thank you in advance for your help

1. I am using linux and got mdfvalidator working with wine without issues.
2. I will with the files from your link and keep you informed or track changes on github

from mdfreader.

I checked and those files are not complying to ASAM MDF standard, these are database dump files, you are try to use the wrong tool.
