Since I last reported on my inability to upload on my laptop (it works well on my wife's laptop) I have tried deleting and reloading both Arduino and Java software. Now I get the following message:
"Error opening file for writing: C:\Program Files (x86)Arduino\java\bin\awt.dll
Click Abort to stop the installation, Retry to try again, or
Ignore to skip this file.
Any support wisdom?
Colin.
