IIS requests to the ISAPI filter for Coldfusion 2023 result in a 500 error.
I have a Dev server running Windows Server 2016 standard. It has plenty of disk space and RAM. I’ve been running CF2018 on it for years. On Monday, I attempted to install CF2023. the install went well (no obvious errors) and the CF administrator ran just fine, so I was able to complete the set up (configuring our DB connection for example).
I then ran the web server configuration tool which said there was already a connection set up, so I removed the connection the CF2018 had and then set up the CF2023 configuration. I checked the ISAPI filter and the Handler Mappings, and the Jakarta virtual directory and they all point to the CF2023 installation.
All that said, I get a 500 error whenever I make a request for a Coldfusion resourse. The IIS logs say the status is 500 0 193. The ‘193’ indicates:
%1 is not a valid Win32 application.
If there were a problem with the first install package I downloaded, I downloaded a second installer, uninstalled everything, reinstalled (as admin) and am still getting the same error.
I’m not sure what step to take next.
