Issue when installing Pandas 0.16 on Windows using Conda
Hi,
I tried installing pandas .16 using conda in windows but am getting the following issue. I tried reinstalling using an admin console but it doesn't work. I've downgraded to 0.15.2 which works again but could use help.

This is my first time posting so if this is not the appropriate channel please let me know.

Thanks in advance
