https://community.blueprism.com/t5/Product-Forum/Utility-File-Management-VBO-keeps-failing/m-p/83381#M34665 Part of my process downloads a file and then moves it to a specified folder. I'm using the File Management VBO to check the directory exists, and then create it if it doesn't. This runs correctly most of the time (I'd say 8-9 times out of 10) but every now and then I get this error at the "Directory Exists" step: ERROR: Internal : Could not load file or assembly '0 bytes loaded from System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. An attempt was made to load a program with an incorrect format. I don't understand how it can be so inconsistent or what this error means, can anyone help? I just can't trust my process to run unsupervised if this step keeps randomly failing.
