"The hole wizard and advanced hole database is not the expected version" (see attached for full error)

I get this message every time I open files in 2017. I recently installed 2018 but my customers are not yet using it so I'm still using 2017. The message started after loading 2018. I have uninstalled 2018 and still get the message. I get and error for each hole that apparently used the hole wizard?

I do not have toolbox. I have SW 2017 standard SP 4.1

Thanks, Chris
