When an user starts an Exor form an error message ‘FRM-40010:Cannot read form ******.fmx’ is appearing.
It happens on running one or some Exor forms.
Usually, it happens when the particular form execution file (*.fmx) is unavailable (is broken or hasn’t been copied to the right directory on upgrading the system).
Go to relevant directory (by default it is c:\exor\bin) on the Oracle Weblogic Server and copy a form *.fmx file there (eg. MAI3801.fmx)
