Windows 10 - Office 2016.
I have large Access application - code in an accdb file with a backend mdb database.
I am constantly adding new developments, doing so in small increments (keeping all previous copies of the accdb file).
Occasionally the latest version of some minor code changes, will fail "File Not Found" on start up.
The initial splash screen has an OK button - and clicking that (when it eventually appears - as it is very slow to appear when this happens) gives a message about "the on-click event failed......File Not Found".
It goes no further and can only be stopped by using Task Manager.
Sometimes if you run the Compile option on the vba code it will come up with a compiler error - but often this will also say "File not found" - stopping (yellow highlight) on the Form Load event for the splash screen.
The only way I have found to get round this is to go back to a previous working code module and reapply the changes. Which works.
Today has been a complete disaster as searching for a solution led me to a Microsoft page that recommended a complete diagnostic check on Office. Despite being dubious I went ahead. After several minutes it eventually completed, then said there was an error and completely removed all Office programs (including Access) from my machine!!!!!!!!!!!!!
Anyone offer any solace?????
