Hello,
thank you for your detailed and quick reply.
what i did was , i just installed the latest geforce experience from nvidia i.e version 1.8.2.0
without deleting the original one and ran the installer. Now, when i right click on the geforce experience icon(<properties) it shows me the "date created" (...2013) and "date modified"(29 march 2014), which means i have updated the software.
Nvidia customer service is extremely bad! and even the community doesn't seem to help that much!
(just questions and questions! ... rarely find answers to them)
Thank you very much!
