python - Slycot Import Error: DLL load failed -

i have installed slycot on other windows machines, running error have not seen before while attempting install on work desktop. usual procedure follows:

install pythonxy download microsoft visual c++ 2008 , sp1 using link http://www.lfd.uci.edu/~gohlke/pythonlibs/ download , install slycot binary provided in http://www.lfd.uci.edu/~gohlke/pythonlibs/

this has worked before, , appeared install no issues, next error when seek import slycot:

>>> import slycot traceback (most recent phone call last): file "<stdin>", line 1, in <module> file "c:\python27\lib\site-packages\slycot\__init__.py", line 5, in <module> slycot.analysis import ab01nd,ab05md,ab05nd,ab07nd,ab08nd, ab09ad file "c:\python27\lib\site-packages\slycot\analysis.py", line 21, in <module> slycot import _wrapper importerror: dll load failed: specified module not found. >>>
