I purchased new PC Lenovo Thinkpad (Win11 Pro 64/CPU Core i7-1270P vPro/ 32GB) just a couple days ago. But I have to return this PC, because I cannot log in to Lacerte 2021. Lacerte 2021 was successfully installed, but try to open and log-in, it will disappear. I am not IT person. I called to Lacerte Tech support and did every things following them. I connected telephone for 7 hours!!! and share screen with Lacerte Tech support with 2 persons. Re-installed many times, using repair tools etc. But I am not able to log in to Lacerte.  Lacerte Tech give-up after 7 hours and told me that this is not Lacerte issue. It will be system defective or other cause. I was planning to install 2021 Lacerte to new PC with Win 11 and transfer all client's data from Win10 PC. Then I can transfer all my client data to 2022 Lacerte in new PC Win11 after lacerte released 2022. But, I decided to return this PC Because I am not able to open Lacerte 2021. I want to know if someone had same experience with me.  And how did  you solved? Is it still too early to switch to Win 11?
