Microsoft Access and PHP8

I have been using PhpRunner for several years with a Microsoft Database with nor problem. Recently it filed with the following message
Fatal error: Source: ADODB.Connection
Description: Provider cannot be found. It may not be properly installed. in D:\domains\amg122.com\httpdocs\new\connections\Connection.php on line 668
I upgraded tp PHPRunner 10.91 and was able to get it to work well under localhost and also with the demo site. However when I posted it to my webhosting site I still had the above error message. I discovered that the php version on my webhost had changed to PHP8. If I change it back to PHP5.6 then my program works well. However, the hosting company informs me that PHO5.6 is EOL and that hey would not be able to support this much longer and that I need to use PHP8. But then I get the error message.
Any suggestions?
