I wrote an Access app for my non-profit organization in 2004 using Access 2000. Since that time I have moved to Access 2007, cannot go any higher or I get massive errors. This has functioned well until I upgraded our pc to Win11. After the transition I still had no problems but after one of the automatic security updates I can no longer view the database window, tables, queries, etc. It shows up in the taskbar but clicking on it does nothing. The database still functions flawlessly but if I need to go to a table to correct some mis-entered data I cant. Any Ideas. Yes I have tried compact and repair, view hidden objects and other ideas from the web to no avail.
It sounds like you are using the Runtime version of Access, rather than the full version. Find msaccess.exe and start it. Does it show the full interface? File > New, can you create a new database and design a table and a form?
