I was wondering about the following Scenario:
I developed a C# application, that generates Excel reports based on the Microsoft.Office.Interop.Excel Assemblies and installed the application on a Windows 2003 Server without installed Excel, but I don't get it to work there.
So basicly: Do I Need Office on the machine, where I want to use the above named assemblies or might it be for other reasons?
Thanks in advance for all well meant answers.
Yes, you need to have Excel installed on your server. Also, there are special licensing requirements for this, so please see:

I am developing a winform desktop application that uses the Microsoft.Office.Interop.Excel library for processing Excel files.
I have included this file in the References section of my program, but when I build it as an exe and send it to another user's computer, they are required to download a Microsoft driver in order to use the Excel integration features.
How can I include the dll when I build my program, so that my users don't need to download and install a separate driver?
Updated to add:
My users all have Microsoft Excel installed on their computers, so this is a different issue than the related question.
Here is the error message the user receives:
As i remember Microsoft.Office.Interop.Excel requires Microsoft Office to be installed on your target machine. I recommend you to use ExcelDataReader which allows you to work with Excel workbooks and does not require any additional drivers etc. Check it out!
I developed a "Reporting App" on C# that creates reports (basically on .doc's and .ppt's formats (using the MS Office interops libraries)) based on some parameters received from the user. Everything works as expected when the app is executed on a Windows Server or computer. The problem is that one costumer's server is Linux based. Is it possible to create Office documents on a Linux environment? Any ideas how?
I am currently using these libraries:
Microsoft.Office.Core
Microsoft.Office.Interop.Word
Microsoft.Office.Interop.PowerPoint
Please help.
You can use the open XML SDK for cross platform or cases when Office is not installed on the hosting machine

I have developed one windows application in C#.Net (stand-alone application). It is basically a Image processing application.
While developing this application I have used Dev-Express controls for better performance. Now I have created the setup file of that application and tried to install it on few machines for testing purpose, while doing this I found that this application is getting install successfully on those machines which has Dev-Express installed on it, but getting failed to install on those machines which do not have Dev-Express setup.
So my question is- "How can I solve this problem..?". Because, as Dev-Express license copy is very costly, "I don't know whether my client will afford it or not". Please Help..!!
You do not need to a separate license for the distribution (see the Licensing FAQ for more information).
However, you need to distribute the corresponding DevExpress runtime assemblies, because they obviously are not installed on clients' machines. This approach is common for distributing 3-rd party products. Consult the DevExpress support for further clarification.
All,
I created a C# console app in VS2010 (.NET4). that hits a database and sends out emails.
It works fine when I run it from VS but deploying the app to a remote server has me befuddled. All I need to do is install this app on (1) remote windows server.
Should be easy, right?
Looking at the publish settings, I don't see anything that will just build it locally without creating an installer (From a CD-Rom or DVD-ROM) and the other 2 options really don't apply either, at least by their descriptions.
So here is what I did so far:
The VS2010 publishing options that I am given are as follows:
Step #1 Picked option 3
Step #2 Place generated files on remote server
Step #3 Ran the setup installer
Step #4 Get this error
Question
Am I approaching this correctly?
If not, what do I need to do?
Thanks
Notice the error:
The application requires that assembly office Version 12.0.0.0 be installed in the Global Assembly Cache (GAC) first.
Refer to this answer and this MSDN question which contains the answer I have quoted below:
We solved it by going into the Applications Files dialog under the publish tab of the Project's properties and changing the office.dll assembly to Include. It had previously been set to prerequisite (auto). --Dave3182
It looks like your application is leveraging Microsoft Office (2003, I think) COM objects. This will require the same version of Office to be installed on your server.
If you are leveraging Office format files (.doc, .docx, .xls, .xlsx for example), you can look into 3rd party libraries that allow you to create the formatted files without Office installed. If you are just using Outlook to send the emails, you should re-implement the feature using the .NET libraries instead.
