Install PHP 7.3 32-bit on Win Sever 2016 with IIS 10

My  employer needs to install the 32-bit version of PHP on a Windows Server 2016 running IIs 10.0.  The OS and IIS are 64-bit apps.  We are using FastCGI with PHP 7.3.10/.  Using the cmd prompt PHP is running fine.  In the browser the response to any php file is HTTP Error 500.0 - Internal Server Error.

So it appears that IIS does not like the 32-bit app.

My first question is will the 32-bit version of PHP run in this environment?  

Yes, I do know that the 64-bit version is much better and faster.  We have a 32-bit driver for our ERP that forces the use of 32 bit applications. 

I can find no useful errors so any suggestions on logging and debugging would be helpful.

Thanks!!
