PuTTY Session Manager failed to export sessions

In my case, FileHelpers.dll was not present in my Putty Session Manager folder - probably because I was using putty tools that had been passed from hand to hand - someone apparently lost that dll over the years :) .

I downloaded the latest official Putty Tools and
1. I found a FileHelpers.dll file in my PuTTY Session Managerfolder, and
2. Exporting Putty sessions to CSV from Putty Session Manager works fine now.

Thanks for the tip above .

Hi Bjoern

Can you confirm which version of windows you are running and if you have the FileHelpers.dll in the same folder as PuTTY Session Manager.exe?

Kind Regards
David

Good day.

I need some advice with the PuTTY Session Manager v0.50. When I try to export the sessions to a CSV file it fails with the following message:

"Failed to export sessions:
Could not load file or assembly 'Filehelpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=3e0c08d59cc3d657' or one of its dependencies."

Any idea on resolving this problem?
