HI, I have a Windows 11 PC that I had Quicken Home & Business 2015 installed on. It's been working PERFECTLY until…my hard drive failed and I had to reinstall everything. Here's my question…When I try to reinstall the program from the original DVD, I get a message telling me I need to uninstall the previous version manually before I can reinstall. I've been operating computers since 1988 and know what I'm doing…I uninstalled, rebooted, then went back and manually deleted some of the leftover files - including in the system register and then rebooted - only to get the same error again. We use this for our small business which we will be retiring from in 2 years after 45yrs so I have NO INTEREST in purchasing new software especially since I've been using this for so long without any Quicken problems. Any ideas on how to get this reinstalled? I need to start my year end reports etc…. Thanks
