I am struggling to get the webadaptor for ArcGIS Enterprise 11.1 working. Please see the error below. Please note the following * Tested 11.0 and it works however 11.1 failed with the error shown below. * Fresh install, win server 2022 * I attempted to use 11.0 web.config with 11.1 and doesn’t work either. * I noted they look every different between 11.0 and 11.1

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

There are new prerequisites at 11.1 that must be applied. Not needed at 11.0 or before.

Have you applied these? I can confirm I've upgraded two clients from 10.9.1 to 11.1 this week and no issues with Web Adaptors - though they were using Server 2019.

Thank you so much for that. I had the .net 6 installed and NOT the hosting bundle. Thanks Scott.

Hi Scott. Which version of the hosting bundle did you use for your successful upgrades? I am using 6.0.18 hosting bundle found here - Download .NET 6.0 (Linux, macOS, and Windows) (microsoft.com).

The link in on the esri documentation to .net 6.0 does not work.

I can't get the web adaptor 11.1 to install as i get this error -

I think it has to do with the dot net 6 version not being picked up by the installer?

thanks

Scott_Tansley

good to know that 6.0.18 is available. I was using 6.0.16. Have you installed webdeploy as well? I used v 3.6

Hi Scott. Thanks for the reply. I did have web deployed installed also. Turns out the issue was actually with McAfee blocking one of the web adaptor processes due to it having a ‘suspicious double file extension’ for anyone else having this issue you can view the error in event viewer.
