Hello, I'm new to DNN and upgrading our platform ultimately to 9.10. But I am recieving thebelow error when upgrading from 9.7.0 to 9.8.0 or 9.9.1. The binding in IIS seems to be poitning to the correct place, and I made previous upgrades from 9.2 to 9.7 without issue. It seems the upgrade from 9.7 to 9.8.0 or 9.9.1 (I've tried both) cause this error. Any thoughts on what it might be? 

Server Error in '/DesktopModules/CompanyName/API-Storefront' Application.

Could not load file or assembly 'DotNetNuke.HttpModules' or one of its dependencies. The system cannot find the file specified.

Did the upgrade complete successfully, and then this error appeared?

This looks like a problem with a 3rd party component (API-Storefront). Did you make sure, you are having a module version installed, which is compatible with latest version of DNN?

I had a similar problem with another assembly. Maybe this idea helps:

Upgrade DNN 9.9.1 to 9.10.x - DNN Open Source Community - Forums (dnncommunity.org)

Happy DNNing!

Thanks Michael, I did try using a system.web.http file version 5.2.7 in the bin directory, no luck either here.

I said "the idea". In your case it should be a file called "DotNetNuke.HttpModules.dll" with the same version number as your DNN installation (to get the version number of an assembly, right click the file, choose "Properties" and go to "Details").

Happy DNNing!
