thank you all for your comments. I just realised that setting the dev environment in windows is turning out to be a real pain.
But I did manage to run the server with the "python trytond" as proposed above, only that I ended up with more errors, a search of this error on google did not yield any results.
Traceback (most recent call last):
File "trytond", line 15, in <module>
import trytond.commandline as commandline
File "C:\Python27\virtualenv\my_project\lib\site-packages\trytond\__init__.py", line 15, in <module>
warnings.warn('Timezone must be set to UTC instead of %s', time.tzname[0])
TypeError: issubclass() arg 1 must be a class
It is probably a good idea to try other environments as suggested, unless someone can come to the rescue here.
thanks anyway
