After all these months, not able to upload any more. George (glavra@yahoo.com".

In Windows 7 ?

In Windows 7 is no Java needed. The Arduino IDE 1.6.1 will run without installing something extra.

Could you remove old versions of Arduino IDE (but not your projects).

Download the zip-file and unpack that. Run it from its folder.
If you still have problems, delete the folder C : \ Program Files (x86) \ Arduino
and use JavaRa to clean up : https://singularlabs.com/software/javara/
