I just install 5.17 on two Windows 11 computers. I used 1. Exit any instances of GNUCash that are running. 2. Uninstall GNUCash 3. Delete the "gnucash" folder located in "C:\Program Files (x86)" 4. Install 5.17 https://github.com/Gnucash/gnucash/releases/download/5.17/gnucash-5.17.setup.exe
Yes, I get a Microsoft message that this might be harmful. I select more information then install anyway. -----Original Message----- From: gnucash-user <[email protected]> On Behalf Of Tom Route36 Sent: Friday, October 16, 2026 12:12 PM To: Wm Tarr <[email protected]> Cc: [email protected]; [email protected] Subject: Re: [GNC] Cannot install GnuCash on Windows I don't think the source matters. I've seen that warning from Defender before for quite a few other .exe files. I think the main thing is to be sure you're getting the installation file from a trusted verifiable source. For Larry's issue, it's probably easiest to just click the "More Info" link (assuming he sees it), and then "Run Anyway". Of course, that also assumes he got the installation file via gnucash.org and https://sourceforge.net/projects/gnucash/files/gnucash%20%28stable%29/5.17/gnucash-5.17.setup.exe/download.
