ok, if you’re on Windows 7, using Pd-extended 0.42.5 and want to use GEM 0.93.1 there’s a few thing you must do.
download pd-vanilla 0.43
download GEM 0.93.1 (not 0.93.0) and install it for pd-extended
in the pd-vanilla zip, open the bin/ folder and search for these 2 files pthreadVC.dll and pthreadVC.lib
copy the 2 files and drop in Program Files (x86)/pd/bin/ folder for pd-extented.
Now, you should be able to use GEM 0.93.1 objects with pd-extended 0.42.5
I've included a zip with the necessary files, but if it doesn't work you know where to get it.
