Hi Govert,

Apologies for a very basic question but I am having trouble installing ExcelDNA Addin for some reason. I have been following your Youtube tutorials, tried multiple times but am getting the following error message:

Error The imported project file "C:\Users\Roy\source\repos\ClassLibrary1\packages\ExcelDna.AddIn.1.8.0\build\ExcelDna.AddIn.targets" could not be loaded. Name cannot begin with the '<' character, hexadecimal value 0x3C. Line 221, position 98. C:\Users\Roy\source\repos\ClassLibrary1\ClassLibrary1.vbproj

Do you mind advising? Thanks a lot for your help and time in advance.

Kind Regards,
Roy

Hi Roy,

What version of Visual Studio are you using?
This is the simplest add-in with VB.NET - maybe you can check whether it compiles on your machine.

Hi Govert,

I am using Visual Studio 2022. I tried your suggestion but still getting an error. Is this error only happening to me?

Error (active) Project "C:\Users\Roy\.nuget\packages\exceldna.addin\1.8.0\build\ExcelDna.AddIn.targets" was not imported by "C:\Users\Roy\Downloads\TestVb18-master\TestVb18-master\TestVb18\obj\TestVb18.vbproj.nuget.g.targets" at (4,5), due to the file being invalid.

Hi Roy,

 

It works fine on my machine,  and I’ve had no other reports of this error or build trouble with this version (or earlier versions).

 

You can try:

*Delete the NuGet package from the cache - you can safely delete the whole directory C:\Users\Roy\.nuget\packages\exceldna.addin\1.8.0 Then rebuild.

*Reference an older version of the ExcelDna.AddIn Nuget package, maybe v1.7.0

*Maybe something on your machine is interpreting the xml files in a different way.The error you show relates to a line in the project file that has an &lt; escaped identifier. Not sure why that would be interpreted differently on your build.

 

The file and line mentioned looks like this on my machine:

 

 

Maybe you have some other tool installed in Visual Studio that might be interefering?
