One fix is to:
- Go to IIS Manager > Application Pools and find the application pool that the website you just published to is using.
- Right click the application pool and choose Advanced Settings.
- One of the very first options is Enable 32-Bit Applications and it is set to true by default. Set it to False. Choose Ok to exit.
Refresh the page and see if your website is working now.
