I have a new iMac with the M3 chip, running Sonoma 14.1.1. I've downloaded and installed the latest Quicken (7.3.2), but it will not run my Quicken file at all. The error message just says it cannot be opened and suggests that I update to the latest version, which is what I have. Occasionally, it thinks I may have it open on another computer (I don't).
I still have my old iMac with an Intel chip, which is also running Sonoma 14.1.1, but its Quicken is 7.0.1. It opens my Quicken file just fine.
That tells me the file is OK. So what do I need to do to get my new iMac to open the file?
