Error reqistering dll on 64bit server.

I wrote a .NET assembly that references the CrystalDecisions.CrystalReports.Engine.dll and the CrystalDecisions.Shared.dll.  I created a installer project that uses Regasm to register the 2 Crystal Report dlls and my dll.  When I run the installer on my Windows 7 machine, it installs just fine.

When I try to install it on a 64 bit server, I get an error 1001.Unable to get installer types in the C:\Folder\ CrystalDecisions.CrystalReports.Engine.dll assembly.  Retrieve the LoadExceptions property for more information.
My project platform and platform target are both set to “Any CPU”.

Could this be because it is a 64 bit server and if so, what can I do about it?  How does one retrieve the LoadExceptions property?

This is the code that my installer is running to register the dlls.  I didn’t write it but it works on my Windows 7 machine.

==========================================================================
using System.ComponentModel;
using System.Configuration.Install;

namespace FileConverter
{
    [RunInstaller(true)]
    public partial class RegisterDll : Installer
    {
        public RegisterDll()
        {
            InitializeComponent();
        }

        [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Demand)]
        public override void Commit(System.Collections.IDictionary savedState)
        {
            base.Commit(savedState);

            // Get the location of regasm
            string regasmPath = System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory() + @"regasm.exe";
            // Get the location of our DLL
            string componentPath = typeof(RegisterDll).Assembly.Location;
            // Execute regasm
            System.Diagnostics.Process.Start(regasmPath, "/codebase \"" + componentPath + "\"");
        }

        [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Demand)]
        public override void Install(System.Collections.IDictionary stateSaver)
        {
            base.Install(stateSaver);
        }
    }
}

I think the Crystal assemblies are 32-bit dll's.  Since, you built your code to "Any CPU" it will run as 64-bit process on a 64-bit machine, and it will choke when trying to load 32-bit dll's.

Try building your application to "x86", and check if the problem goes away.  Alternatively, you can try to confirm if that Crystal dll's support 64-bit.

I hope this helps.

Thanks for the help.  I set the cpu type to x86 and rebuilt the project but the installer is still giving me the same error.

Are the Crystal dlls that come with VS2008 a MS product or a SAP product?  How can I find out if the Crystal dlls that come with VS2008 will work on a 64 bit OS?  Also, do I need to buy a license to include the Crystal dlls that come with VS2008 with my application?

Thanks!

I did further research on this issue.  Just installing the Crystal dll's is not enough.  You need to install the Runtime Packages for Crystal Reports Basic for Visual Studio .NET 2008, which can be found on the link below:

http://resources.businessobjects.com/support/additional_downloads/runtime.asp#09

Crystal is a SAP product.  Read the license agreement on the installer above for more information.

BTW, to determine if a dll is 32 or 64 bit. Open the VS command prompt, then execute the following command:

corflags "<complete path to assembly>"

Check the PE and 32BIT flags:

    AnyCpu: PE=PE32   32BIT=0
    x86:        PE=PE32   32BIT=1
    x64:        PE=PE32+ 32BIT=0

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Thank you again.  I will research these other dllls soon.  And I understand what you are saying, "Just installing the Crystal dll's is not enough." but that is something I will deal with later.  My problem is not running my program.  My problem is getting the Crystal dlls installed that my program is referencing.

Also, on that page that the link took me to, it says ...

This file contains the latest install packages required for deploying .NET applications using Crystal Reports Basic for Visual Studio .NET 2008 runtime.

Am I really using Crystal Reports Basic  when I am referencing the Crystal Report dlls that come with VS 2008 out of the box?  I mean I can download the other dlls and incorporate them into my installer program but I just want to make sure these are not 2 different things.

Thanks again!

You need to execute the Crystal runtime install as part of your installer.  As I understand, the Crystal dll's require a runtime environment that need to be installed on the server also.  Just deploying the Crystal dll's referenced by your project is not enough.
