Could not access ViewNX-i yesterday. Removed the app and reloaded from the Nikon website. Worked fine except for that one shot I put in the abstract thread. Today I transferred my shots at Wako from the D7100 using ViewNX-i and after a successful transfer I closed the app (guess I shouldn't have done that). Now I get a message - this app can't run on your PC. I removed and reloaded and still get the same error. Any one else having problems using ViewNX-i?
