I have one native shim add-in project including C# class libraries.
Add-in works fine in windows OS (By using WIX).
Is it possible to load this add-in on outlook of MacOS?
If so, How can i do that ?
Is it possible to load this add-in on outlook of MacOS?
No, it is not possible. There is no COM technology available on other platforms. COM add-ins can be run on Windows only.
If so, How can i do that ?
There is no way to port an existing solution. You may consider developing a web-based Office add-in to support multiple platforms and devices. See Build your first Outlook add-in to get started quickly.

I have developed an addin for MS Office Word using 2010 project template (VSTO C#)
It is working in Windows Office Word. Now I need to install it in Mac OS ? Is it possible ?
Do you have any link ?
The VSTO technology is not supported on Mac OS.
If you need an add-in that runs on both platforms, then you need to use the Office JavaScript "web add-in" functionality (which also works in the on-line versions of Office and on iPad, by the way).
This is a good place to start in the official documentation: https://learn.microsoft.com/en-us/office/dev/add-ins/overview/office-add-ins
For support, use the office-js tag here on Stack Overflow.
"If you want to use Interop, then the component should be installed in
the system. Otherwise, it won't work."
I have a WinForm application, that is used by many users in several SO (WinXP, Win7, Win8.1, WinServer 2008, WinServer 2012)
In development, I use a COM component (Outlook, SpeechLib,...).
Two keys:
Some users cannot installed the component. Or they haven't installed it.
Another users can be installed the component.
Any programatically way to:
avoid the application fails for the users that hasn't installed the component
the application works for the users that has installed the component
?
Notes:
Programmatically way to determine whether a particular COM library DLL has been installed or is installed. Anyways, if a particular COM library not installed, the target is that my source code not fails in runtime in that machine without that COM installed.
For example, for Excel, Word, Outlook COM (ActiveX), SpeechLib (Microsoft Speech Object Library), etc
I could have source code like this:
SpeechVoiceSpeakFlags SpFlags = SpeechVoiceSpeakFlags.SVSFlagsAsync;
SpeechLib.ISpeechVoice speech = new SpeechLib.SpVoiceClass();
// ....
Or anyways using Outlool application class, or Excel.Application, etc.
Type officeType = Type.GetTypeFromProgID("Excel.Application");
if (officeType == null)
{
// Excel is not installed.
// Show message or alert that Excel is not installed.
}
else
{
// Excel is installed.
// Continue your work.
}
My old issue, but not solution:
Detect Outlook installed and load dynamically INterop.Outlook
Detect Outlook installed and load dynamically INterop.Outlook
I have a Windows Forms application in VS2010. It has a reference to
Interop.Outlook (2003). Then, I have reinstalled Windows XP and
VS2010, but not install Outlook.
Now, the project not compiles.
I think this, my application will not work if Outlook not installed in
machine that my program executes on.
I need to know if I detect Outlook installed, and load dynamically
Interop.Outlook.dll (for using the Outlook PIA or Embedded Interop
types in .NET 4).
If the machine has Outlook (2003, 2007, 2010, perhaps need code to
detect version and do compatibility of Outlook versions) installed,
the application works fine with functionally Outlook.
If the machine hasn’t Outlook installed, (in runtime) the application
works fine without functionally Outlook. I think, If the machine
hasn’t Outlook installed, (in runtime) the application fails because
references (in source code) to Outlook.Application class?.
In development machine, the application works because Outlook (and
COM) is installed in the machine.
Any sample source code or goog patterns and practices about it??

I posted this elsewhere, but here's the code to detect if Outlook is installed. Basically, it tries to get the Outlook automation object.
using System;
using Microsoft.Office.Interop.Outlook;
class Program
{
static void Main(string[] args)
{
var outlookType = Type.GetTypeFromProgID("Outlook.Application");
if (outlookType == null)
{
Console.WriteLine("Not installed.");
}
else
{
var app = Activator.CreateInstance(outlookType) as Application;
Console.WriteLine(app.Name);
}
}
}
For SpeechLib, I think the right way to detect it is to just try and create a "new SpVoice()" instance wrapped with a try/catch. If it fails, then assume speech is not installed. Again, embedding the interop will allow you to avoid runtime type load issues.
Hope that helps.
I am trying to write a program that modifies Office files (word, excel) programmatically using C#. Before continuing with my project, I would like to know if the COM Interop can be used in OSX by utilizing Wine, and if so, can this be done in Linux as well?

To detect if Outlook is installed, look for the "Outlook.Application" ProgID.
From an installer, look in the registry for HKEY_CLASSES_ROOT\Outlook.Application
At runtime, you can do this:
using System;
using Microsoft.Office.Interop.Outlook;
class Program
{
static void Main(string[] args)
{
var outlookType = Type.GetTypeFromProgID("Outlook.Application");
if (outlookType == null)
{
Console.WriteLine("Not installed.");
}
else
{
var app = Activator.CreateInstance(outlookType) as Application;
Console.WriteLine(app.Name);
}
}
}
To avoid the problem of dynamically loading the interop, you should set Embed Interop Types to true for Microsoft.Office.Interop.Outlook.Interop.dll
check the Installer APIs to detect the install state of Outlook or use one of the method described here.
I am creating an app in C# using the .NET COM Primary Interop Assemblies. I was wondering if this will be able to open and read files from both Project 2003 and Project 2007. Also, does Project have to be installe don the computer that is running this app?
That's Yes and Yes. You'll have to use the 2003 PIA, Office versions beyond this are backwards compatible with older COM interface specifications. But of course you won't be able to use 2007 specific features. You can't do anything with Project if it isn't installed on the machine. Project 2003 isn't likely to be able to read Project 2007 files unless the file was saved in 2003 format. No problem the other way around.
