I have installed old version of Quicken on a spare laptop (as mine is currently broken). No problem doing the installation but when trying to use it have to activate it first. I input my Quicken Installation key and it attempts to contact Reckon to verify / activate but then fails with unexpected error. Error code = 7083.
Reckon won't help me troubleshoot because it is old version (Quicken 2009) and directed me to Reckon community (community.reckon.com) but no reports of this error message there.
I'm pretty sure I used to have this happen to me too and had to get my account reset a few times before I gave up. It's so old now that they won't talk to you. I was trying to use it in a virtual machine on my Mac.
