Troubleshooting SEHException and AVX Support in IronOCR
Unhandled exception: System.Runtime.InteropServices.SEHException
This issue is commonly encountered on machines using older Xeon, Celeron, Pentium, or Atom processors that lack AVX support.
Support for non-AVX processors was added in IronOCR version 2022.8.7804, so please upgrade to a later release.
// Example: Checking AVX support programmatically in C#
using System;
class ProcessorFeatures
{
// Main method to check AVX support
static void Main()
{
// Check if the machine's processor supports AVX
if (IsAvxSupported())
{
Console.WriteLine("AVX is supported.");
}
else
{
Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.");
}
}
// Function to determine if AVX is supported
static bool IsAvxSupported()
{
return System.Runtime.Intrinsics.X86.Avx.IsSupported;
}
}' Example: Checking AVX support programmatically in C#
Imports System
Friend Class ProcessorFeatures
' Main method to check AVX support
Shared Sub Main()
' Check if the machine's processor supports AVX
If IsAvxSupported() Then
Console.WriteLine("AVX is supported.")
Else
Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.")
End If
End Sub
' Function to determine if AVX is supported
Private Shared Function IsAvxSupported() As Boolean
Return System.Runtime.Intrinsics.X86.Avx.IsSupported
End Function
End Class' Example: Checking AVX support programmatically in C#
Imports System
Friend Class ProcessorFeatures
' Main method to check AVX support
Shared Sub Main()

If IsAvxSupported() Then
Console.WriteLine("AVX is supported.")

End If
End Sub
' Function to determine if AVX is supported
Private Shared Function IsAvxSupported() As Boolean
Return System.Runtime.Intrinsics.X86.Avx.IsSupported
End Function
End ClassIn this example code, we use the System.Runtime.Intrinsics.X86.Avx.IsSupported property to determine if the processor supports AVX instructions. If AVX is not supported, it's advisable to ensure you are using a version of IronOCR that includes support for non-AVX processors.
