can not open OpenOffice

[Bill Alles]

Hello.  I recently updated my Mac to Catalina version 10.15.1 and since doing 
so, I have not been able to open the OpenOffice program. It tells me to contact 
the developer, so that is why I am writing. Please advise as to what needs to 
be done so that I can access the OpenOffice program again.Thank you for your 
assistance,                                                  Bill
