Hi @MasterCodeIT,
Can you check that the following assemblies are included in your build output?
WebView2Loader.dll
Microsoft.Web.WebView2.Core.dll
Microsoft.Web.WebView2.WinForms.dll
These assemblies must be located under the same directory as your app's exe, possibly under a architecture/platform subdirectory.
Closing on lack of activity. Please reopen with further details if this is still an issue.
Apologies as I was away on a trip.
Yes, assemblies were in the same directory
Hi @MasterCodeIT,

We reproduce this issue with all versions since the 1.0.2651.64 version (included) if we build our installer with .Net8 and if (only if) the WebView2 SDK dependency is transitive.
We test with a direct dependency : the dll are copied to the output.
With a transitive dependency : dll are not copied (except WebView2Loader.dll) and we get a FileNotFoundException for Microsoft.Web.WebView2.Core.dll on runtime.
