System Info: Windows7 x64 and .net Freamwork 4.0

I can run with 2.0 to create the software, but run dna-addin report error:


The software can run normally on other machines,which is also Windows7 x64

This add-in is trying to load the .NET Runtime version 2.0. Is that what you're expecting?
Could you post your .dna file?

Now, it might be that .NET 2.0 is not installed on this machine.
Otherwise there is some error in trying to load the .NET framework meta-loader. Is there a file called "excel.exe.config" in the Office director next to Excel.exe? If so, it might contain some entries that constrain which .NET version can be loaded into the Excel process.
Could you check and post that file if it exists?

This discussion also seems to mention the same error:!topic/exceldna/ugb1vrJJ1zY
Re-installing the .NET Framework resolved the error in that case.

thanks govert,I have found the method to solve the problem.

I make a File named Excel.exe.config in The Excel InstallRoot,content like this:



<supportedRuntime version="v2.0.50727" />
