Yes, I was using the extension packager to bundle my extension.
There is a 32bit and 64bit version of ID CC and ID 2014 available. Plugins built for that specific architecture must go into the corresponding folder in Windows. I know that there is a possibility to define the behaviour in the manifest file using the manual packaing tools. I would be interested how other people do it. I am also having major problems copying the right plugins in the right location..
