I have some new Unos and have installed the Arduino software on a number of machines on my network. Our operating system is Windows 7 (64 bit).
I have checked the Board is set to the correct type and the correct Com port is selected.
IDE 1.6.10 is installed and I have tried 1.6.5 and 1.6.8 as suggested by some Forum respondents in earlier posts.
The problem occurs on different computers and using different boards. I have also tried using the reset button both before and after selecting upload with various length delays.
The installation was done with administrative privileges and the compile tested with both user and administrative credentials.
Attached is the output from the verbose logging when the compile is attempted.
Interestingly enough the output shows 1.6.8 whereas Board Manager shows 1.6.10 as installed. I don’t know if this is significant.
