1. There is something wrong with the permissions on the TEMP directory
unrelated to R. Remove everything in that directory and make sure that
you have write permission on TEMP. Its probably easier to do that
through Windows Explorer.
2. Regarding the comment on the paths, I don't think the Tools or R
paths were correct. The tools path should end end in bin but it did
not. Also there are additional components for gcc that I think were
missing. Also the R path ends in x64 (or i386 if you want 32 bit)
but yours ended in bin. Note that if you use R.bat or Rpathset.bat
consistently you don't have to set up your path in the first place.
Its basically configuration-free.
will show the values its heuristic found.
3. Regarding Admin rights I think its best to keep everything as
standard as possible which means installing R itself into C:\Program
Files\... tree which is where it goes by default and that requires
Admin rights to do.
