When I download the gecomapi_win32_pi16_v010_pi.dll plugin
from the Open cpn plugin
page and put it into the plugin folder then go to tools and then plugins its not there in the list.
Ive downloaded it a few times and tried with Open cpn
versions 3.0.2 3.2.2 and 3.3
I think my methods are OK as I have successfully downloaded and enabled a few other plugins without a problem.
Iam using XP-SP3
