Posted on by 127
After updating to version 2.59.163.25230 all flows stop on the "Display custom form" action, with the following error:
System.IO.FileNotFoundException: Could not load file or assembly 'AdaptiveCards, Version=1.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
File name: 'AdaptiveCards, Version=1.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

    The problem was caused by some missing files.
    After update from v 2.59.154 to 2.59.163 the following files are no longer in PAD directory and must be copied over:
    - AdaptiveCards.dll
    - AdaptiveCards.Rendering.Wpf.dll
     
    No more errors after that.
    Also can be solved uninstalling and reinstalling PAD.
