Can't load COM object to display my reports

Question

Hi,
We have created a few reports using Crystal Report with visual studio 2008. Works fine on our development machines.. but not on the server. I installed the redistribuable x86 on the server, but I always get this error (see below). I tracked down the error number to be 'access denied'.. I don't know which directory/files I need to give access.
I'm clueless.. any help would be greatly appreciated!
Server Error in '/' Application.
Retrieving the COM class factory for component with CLSID {5FF57840-5172-4482-9CA3-541C7878AE0F} failed due to the following error: 80070005.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {5FF57840-5172-4482-9CA3-541C7878AE0F} failed due to the following error: 80070005.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically \ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

Hi Martin,
Have a look to this thread :

Check that have you applied runtimes on server if not then
Try with this link to download runtimes :
