Installing Quicken to a new PC

Adding my 2 cents because I spent 2 hours trying to do the same thing last night. Bought a new PC (Win11) and wanted to migrate things over from a Win10. I thought, I'll just install Q2017 (I keep the install files), then copy the QDF over to the new machine and I'll be in business. Nope. Got the dreaded blank screen (after a perhaps 1 second flash of my data, btw, so it was there somewhere). After googling and uninstalling/reinstalling about a dozen times, I found a thread that outlined the procedure that actually worked for me. Purely copying over the Quicken.ini file didn't work; I'm not sure which is the critical step here - the Revo Uninstaller, or the patch, but I will say that the issue seems to stem from Quicken leaving remnants of itself all over the place such that if you don't follow the instructions from a clean machine, you're screwed. That said, Revo goes above and beyond the other install and file/directory delete methods that you'll see, even those posted by @Chris_QPW (kudos to him/her for supporting Quicken for us commoners when the company won't). Revo not only uninstalls Quicken, but it scrapes the registry and HDD to find any last traces of the install. I selected all/delete when it gave me the option.

I don't know how to link to the OP for these instructions, but again after trying many different combinations of install/uninstall/delete files/folders/using Chris's QCleanUI/etc, the following procedure worked for me (with my edits):

1. Use Revo Uninstaller to clean up an existing installation and remove the leftover files (I did not clean the registry as the leftover keys did not seem too important). [EDIT - I selected all registry keys and files/folders to delete. This was a new machine so I wasn't worried about breaking other Intuit/Quicken software. I just googled Revo Uninstaller and downloaded the most recent version from the site]
2. Install Quicken 2017 [EDIT - I used the original install files, and selected to close the program rather than run at the end. Also note that the installer, which has internet access, auto updates to 20.6, which was the version running on the Win10 machine]
3. Replace the quicken.ini file in ProgramData/Intuit/Quicken/Config/ [EDIT - copied from the Win10 machine]
4. Install the patch (QW2017R20.5MPatch) [EDIT - Downloaded from Chris's website. Counterintuitive patching 20.5 over 20.6 but whatever so long as it works]
5. Run Quicken
6. Select Restore backup option using your .qdf file as the source or just use your existing .qdf file [EDIT - I used the restore option, which I had done previously in attempts to get it to work. I don't really think it did anything]

In the end when I finally ran it after 2 hours of repeated un/reinstalls, and my data was on the screen for more than a split second I felt like cheering. That said, it's pretty crappy (although not unexpected I guess) for a company to abandon users that don't want to upgrade to a subscription service. I don't use any auto reconciliation, web or bank connections, etc, Quicken is just an electronic checkbook basically, for me. It's just too bad that there aren't any basic softwares like this in the marketplace that don't suck (I was originally a MS Money user before MS torpedoed that).
