I cannot see why its not working for you…
I’m now running pd49-1 64 bit, and its also working fine…
yup that’s what I installed, without issue.
Ive also just redownload the OscRemoteDisplay from patchstorage, to just check its ok,
and its fine BUT I did include the 32bit mrpeach dlls used, which are not appropriate for 64 bit, but PD just said, it could not load them, and then seemed to proceed to use the ones id downloaded via deken. (you can delete the externals folder to get rid of the warning)
you seem to be having an issue with the mrpeach externals but its unclear why,
when it works for me from a fresh install here?!
perhaps redownload from OscRemoteDisplay from patchstorage, if you didn’t download it in last few days.
and delete the deken folder and try again…
(perhaps you had an old install with a different architecture, or another package than includes routeOSC?)
…. this is why I don’t like windows much, its full of these little potholes 
theres Lemur and Pd for now…
someone has put together a web editor for the rPI for orac, but currently that involves installing a stack of stuff, which is not easy on the nebulae - my hope is to simplify this, but ive no time for this in next month or two.
