Commented Unassigned: ASP.NET MVC: there is no package called 'twitteR' [162]

People,
I am having the same issue as other users, only that adding R to path didnt work.

I tried adding both folders, i386 and x64, so my path variable is as follows:

C:\Program Files\R\R-3.1.2\bin;C:\Program Files\R\R-3.1.2\bin\i386;C:\Program Files\R\R-3.1.2\bin\x64;C:\Program Files\R\R-3.1.2\etc;D:\RProjects\sum4me\TestRIntegration\Sum4Me.MVC\bin;C:\Users\El Gordo\Documents\R\win-library\3.1;C:\Program Files\R\R-3.1.2\library

So, I am including not only R, but the current paths to the application just in case they are required.
I have inspected using procmon and the files seems to be being loaded correctly.

Any ideas what else should I try?
Thank you.



Comments: Since IIS Express generally runs as your user identity, I'd expect R to be able to find the package in your user account's R package folder. Can you load other external packages, or just not this one?
