April24, expose error with setClipboard (#17)

* try to get win32 function running... (solved after win32_postinstall ran without errors, cleaning up a lot of pywin32 installs was needed, see dictation-toolbox/natlink#193)
* simplified extenvvars, getFolderFromLibraryName,
* try to specify setClipboard function spurious error, (issue #16)
