ALERT: Quicken Classic for Windows fails to install under latest Windows 11

rloeb

Problem is that the install contains an unsigned printer driver, which Win11 no longer allows. There's a workaround, but it involves rebooting into safe mode, disabling the driver signing requirement, then installing. (The latest Windows bug makes this especially complicated because it doesn't allow shutdown or restart…)

I would try updating your printer driver, reboot your computer, and then try installing Quicken.

@Grammy605 , Microsoft issued a warning about KB5074109, suggesting users experiencing issues to uninstall it. And presumably yesterday's KB5078127 resolves some of them but not all. I don't think that is your problem but just FYI.

Install aborts. Quicken, however, appears to work, this time, after 3 attempts. I won't attempt to print to PDF!

Thank you for your reply,

To clarify, when you say it appears to work after 3 attempts, do you mean after 3 attempts to install, or do you mean you had to try to open the program 3 time before it worked?

Thank you!

I'm unsure whether to piggyback here (since I have seen the same installation error as the above screenshot) or somewhere else. I'm new to this support forum, but not new to Quicken or computers in general.

I had to reinstall Win11 today (long story but fairly straightforward). When trying to reinstall Quicken Classic for Windows with the exe file on the site, I got the same error message as the OP. I tried installing with an earlier version of the exe file (from July 2025) and that installed. Kinda. :) Let me add here that I always let Quicken search for updates every time I open it (which is daily), so it should have been updating all along. (Has it been updating, though?)

When I open Quicken after this reinstallation, I see this:

So, yay, it found my data file. But when I click on OK, I get this:

I've uninstalled and reinstalled a few times now, and I always up with a truncated version of the menu items available inside the program, which means I don't have options the Support articles say I should use (like converting data files or restoring a backup file).

I used the Find Quicken Files option and seemed to have found my data file again, but when I clicked on it to open it, it cannot open the file. You know, the same file I had open about two days ago (and just about every day before that) on this same machine, before I had to reinstall Win11 and then tried to reinstall Quicken.

Nearly everything else I've had to reinstall today went smoothly. Oh, and when I tried to see my Quicken profile/account on the website, I got THIS error when I clicked on My Account:

Honestly, I'm ready to tear my hair out.

Unless you have the same issue, everyone can disregard my previous screenshot-laden comment here. Here it is, a day later, and when I opened Quicken, it was fine. I hadn't even rebooted my computer since posting last night.

I haven't a clue what changed, but here we are. :) Quicken, heal thyself.
