using MS VStudion 2012 with latest visual micro.
arduino 1.6 is installed.

Iv'e tried a very simple code using visual studio. the sketch is OK (no bugs) and all I get is this error:

Compiling 'sketch_aug01a' for 'Arduino Nano w/ ATmega328'

Error compiling

I have no idea what is the problem???

On the arduino 1.6 it compiles good.

Hi,

We do not yet support arduino 1.6.2 and 1.6.3 which were released a week or two ago.

We currently recommend installing 1.6.1 from last month.

You can find links to the older arduino ide versions on our download page and at the top of the home page.

We will release support for 1.6.2+ during the next week. It contains more significant changes that normally found in a point release :)
