Report Microsoft Jet Database Engine Cannot Open Home Manage 2020 in HomeManage Support Posted May 22 I had this issue once too: This may be your problem.... After much work not described here I finally figured it out. "I finally figured it out. I am using BitDefender as my security suite. When I updated BitDefender to 2020 edition it blocked HomeManage from accessing my secure folders. Once I saw that it was easy to allow HM access to the HM folders!" Back in action!
