I manually deleted the 1.6 IDE version to install the new version.
I did not know that the upgrade itself would do the replacement. Now it shows a warning that will delete the old version but there is no more version on my laptop.
Now I ran out of the old one and I can not install the new version.
Restore the deleted folder from your recycle bin and then try installing again.
Additional clean up instructions attached
CLEAN UP BEFORE INSTALLING ANOTHER COPY OF THE IDE OR ARDUINO CREATE.pdf (347 KB)
After following the cleaning instructions of the files that still left traces of my old version, I was able to download the new version. The CCleaner aplication is very good.
Thank you ballscrewbob.
Your help was incredible.
Glad they were of use..
The two application I suggest are based on quite a bit of experience.
Dont blame me if your computers seems a little faster after using them.
It is worth using them on a regular basis too.
