Redmine

Hello!

My problem is when i am trying to apply putch which i download from here (issue 13711 run through CR/LF converter), i get the following mistake:

C:\Users\R.Romanovsky>c:\BitNami\redmine-2.3.0-0\git\bin\patch -p0 < c:\BitNami\redmine-2.3.0-0\patchwin.diff
can't find file to patch at input line 1
Perhaps you used the wrong -p or --strip option?
File to patch: c:\BitNami\redmine-2.3.0-0\patchwin.diff

patch: ** can't rename `c:\BitNami\redmine-2.3.0-0\patchwin.diff' to `c:\BitNa
mi\redmine-2.3.0-0\patchwin.diff.orig' : Permission denied
