Assemblies not found

Question / Problem

TreeSize Professional shows the error "Assembly not found - A .NET assembly could not be loaded." on startup and then terminates.

Answer / Solution

TreeSize requires a few libraries (DLLs), like "Jam.Interop.dll" or "ChartAssembly.dll", in addition to its .EXE file to work properly. Please reinstall TreeSize, this will make sure that the two files are copied to the correct directory.
