Aspose.Tasks Product Family

Hi,

When I try and open MPP file created with MSP 2016 I get the following error: “Arithmetic operation resulted in an overflow.”

I am using the following sample code:

namespace AsposeTests
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var project = new Aspose.Tasks.Project(@"testproject.mpp");
        }
    }
}`

Details:

  • Visual Studio 2022
  • .NET 4.8
  • Windows 11
  • Microsoft Project Professional 2016 (version 2206, build 15330.20230)

@aubza,

this is a known issue related to changes in MPP structure introduced by update 16.0.15330.20230.
The fix will be released in v. 22.7. (E.T.A - this week).
