I tried that.  I did have to change some permissions but it still didnt fix the issue.

Any other ideas?

I have tried uninstalling the Uno driver several times.  It is set to com3.  I have a feeling that it is having trouble talking to the com port.  Any other ideas?  I do believe its a computer problem and not an uno problem.

My uno board worked on this computer at one time but I dont know what changed since then. 

I am running Windows 7 x64.  Usb port to the Uno board.  the device manager says there is a Uno board on com3.  The compiler list the board as an Uno on Com3.  When I try to write any program to it (blink.ino) I get an error.

F:\arduino-1.0.1\hardware\tools\avr\bin\avr-ar: unable to rename 'core.a'; reason: Permission denied[/i]

I have tried the Uno board on another computer and it works fine.  I have a feeling it is not communicating to the Uno thru this com port.  i have tried uninstalling the driver several times with no luck. 

Any suggestions?  I did go thru all the trouble shooting ideas but didnt find anything that worked.

Thanks in advance...
