I'm not aware of any installation of python. I have an LyX16 folder with a Python subfolder and an LyX 20 folder also with a python subfolder. The former contains python26.dll and python.exe. The latter contains python 27.dll, python.exe, and pythonw.exe.
The original error message, which referred to "python -tt" occurred while I was running LyX 1.6.7. When I switched to LyX 2.0.0 none of the error messages referred to python, but I still couldn't convert. Details in the string of messages between me and Richard Heck.
