If you have an older version, One of the SuperUsers has posted the update patches for older versions (2000 and newer) of Quicken

Don't know if this note will help with 2016. Quicken 2017 started out using a Intuit ID, not a Quicken ID. Any patch version earlier than R11 is going to be trying to log into the Intuit server which no longer exists.
RConn said: Hello everyone, what a great community with lots of suggestions. I tried re-installing the software with no internet, but the same thing happens -- it asks for Intuit password. I tried downloading and installing the patch R19.5 but got an error message because MSVCP120.dll cannot be found. Any other suggestions? Thanks again, you are all so much more knowledgeable than I about these things.
RConn said: I downloaded the Visual patch, reinstalled the R19.5 patch and then uninstalled and reinstalled Quicken, but nothing works. It always goes back to the sign in screen, which I can't get past with my old log in. I think I might have to give in and subscribe, which is infuriating. Almost 30 years of family finances down the drain if I don't. Ugh! Thanks for the suggestions though.
