Unable to create an excel instance when trying to load an addin. RRS feed


  • Hi Sridhar,

    When you change the Framework to 4.0, your resources are not converted to match.  First, make a backup copy of your project.  Then, try the following.

    Search for "" across the entire solution.  This will locate each of your .resx files, which contain "Version=" references. Change these to "Version=" globally.

    Clean and try a build and see whether that improves things.

    Good luck!
