[Solved] Can't Upload with Arduino IDE after install of Atmel Studio 6

Hi again CrossRoads,
Thanks for taking the time to reply.

Unfortunately that does not seem to work.
I even assigned the Arduino UNO a new com port to see if that would help.

Seems at the moment whatever I do I get the same stk500 failure comments whenever I try and upload.

Just as a matter of interest, I set the board to UNO and the Serial Port to 15 my newly chosen one.
Under programmer I have the following menu options:

AVR ISP
AVRISP MkII
USBtinyISP
USBasp
Parallel Programmer
Arduino as ISP

As I have never really paid any attention to these, are they correct, do I need to be concerned about them (one)?
Maybe if I uninstall Arduini IDE and reinstall would that help, do you think?

Appreciate the help as always, kind regards,
