I get the following error when I type the command Needs[" (i.e., after typing the symbol " after Needs[ ) Also, I noticed recently Wolfram Support doesn't seem to reply to any case IDs which is really worrying. I like to know if anyone else...
Thank you very much for the reply. I still get "False" as output for CUDAQ[]. As you suggested I would contact the Mathematica Technical Support. Regards, Manickam
