COMException error on web forms.

Question

User1146927980 posted

I have an older website created around 2003 on my Windows 8 X64 bit machine.

I am using Visual Studio 2012 Professional to open it on my development machine.

The website runs fine in production (Windows Server 2008) but when i download the code to run on my machine and run the website from Visual Studio 2012 i get the following error:

Retrieving the COM class factory for component with CLSID {5C2EA2BC-4F5D-11D4-A1CF-C1BD8A54860E} failed due to the following error: 80040154.

The error happens on line : Public MapExtents As New Asp.Map.Rectangle

Imports AspMap
Imports ADODB

Partial Class MapImage
    Inherits System.Web.UI.Page

    Public Width As Integer = 400
    Public Height As Integer = 300
    Public Shape As String = ""
    Public MapExtents As New AspMap.Rectangle
    Public ShowBattalions As Boolean = True
    Public UseFilters As Boolean = False
    Public KeepFiltersOnRestore As Boolean = False

The web site is on .NET Framework 2.0

Any ideas?

Hi,

According to the error message, the .NET version may caused the error message.

There is a similar thread:
