Hi, I did solve the issue. Last weekend, I downloaded and installed the programs for 2018-2022 (first year using it was 2010), only to find that none of them worked. Just like you had said, the login screen disappeared before I could log in. Decided to let it sit a few days then tried again. Things I did the first time: Started with 2022 and worked backwards. I didn't restart after each year, just installed them all and then restarted the computer. This morning, I deleted the 2018-2022 Lacerte programs off the new computer. Then, I downloaded a new Windows 11 update. I had updated Windows 11 last week, I thought, but there was another update this morning so I updated it. I loaded the 2018 program first, with the "custom" setting so I could pick and choose the programs to download. The "automatic" was set to install on a network, and I use a stand along. I'm a sole proprietor with only one computer. I then restarted the computer and opened the 2018 Lacerte program. It opened no issue. Not sure which thing I changed helped to solve the problem, but now I have 2018-2022 loaded and all working. Good luck!
