hi, once I had a problem with threads in a non-threaded application (!), because Windows (each version in its own way!) creates threads anyway to speed up (and crash) loading time, the problem was an incorrect version of a self-registering DLL, that's not what you get here but the timing is the same, you can do nothing on Delphi IDE or on your code because the error appears before any code is executed; I found the problema using MadExcept, you can try this or Eurekalog.
