I try to replicate on my own software but none of the proposed solution had cleared the problem with the assembly and since your error messages were 1:1 the same as for me I would be interested to know if it works and if so to try to think out why. Neither Shlwapi.dll nor gdiplus have cleared the problem with the license server.
