How about telling us the exception message, and what's different ( such as different office versions ) between the two machines ?

It is the same version of office, it's office 2007 plus, thank you verry mutch.

OK. But what error message you are getting ?
I think (just a guess) that you dont have correct filepath. i.e. you are using D:\xyz and D: is not there or xyz is not there.
or try this.
in Office 2007
*) Open the 2007 Microsoft Office system application in question. Click the Microsoft Office button, and then click Application Options.
*) Click the Trust Center tab, and then click Trust Center Settings.
*) Click the Macro Settings tab, click to select the Trust access to the VBA project object model check box, and then click OK.
*) Click OK.
Or try opening excel application (manually) and then run your code.

But what is the error message you are getting ?
Try this one.
1. Click Start, click Run, and then type DCOMCNFG. Select the application that we want to automate. The application names are listed below:
2. Microsoft Excel 97/2000/2002/2003 - Microsoft Excel Application
3. Click Properties to open the property dialog box for this application.
4. Click the Security tab. Verify that Use Default Access Permissions and Use Default Launch Permissions are selected.
5. Click the Identity tab. Verify that The Launching User is selected.
6. Click OK to close the property dialog box and return to the main applications list dialog box.
7. In the DCOM Configuration dialog box, click the Default Security tab.
8. Click Edit Defaults for access permissions. Verify that the following users are listed in the access permissions, or add the users if they are not listed:
SYSTEM
INTERACTIVE
Everyone
Administrators
OfficeAutomationUser
IUSR_<machinename>*
IWAM_<machinename>*
* These accounts exist only if Internet Information Server (IIS) is installed on the computer.
9.Make sure that each user is allowed access and click OK.
Click Edit Defaults for launch permissions. Verify that the following users are listed in the launch permissions, or add the users if they are not listed:
SYSTEM

I don't believe that the .NET email classes have ways to set a proxy server.

Hi,
I want to access the data of a PDF file which is opened on IE using BHO.
Using a Browser Helper Object, how can I come to know that a PDF file is opened on IE.
The BHO in the following link is helpful for retrieving data of web pages.
http://www.codeproject.com/KB/cs/Attach_BHO_with_C_.aspx?fid=447248&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=51&select=2421069
But how the PDF file data can be retrieved?

I will be using a IE toolbar button to mark it...
But how can change it so that i can read the encrypted html?
Thank you

We didn't need to see all this code. So, you're saying you can decrypt it, but you want to display it in IE via a toolbar ? So, you want to intercept an HTTP request and decode it, right ?
Does it have to be in a toolbar, could it be in an app that contains an IE control and then does the HTTP request ?

No its not.
You obviously do NOT know what you are talking about, the microsoft .net framework is not something you can import anything into, its a code for running applications.
I suugest you get some books about .net and read them before going any further.

I suggest you need a new keyboard first. Your period (".") key is malfunctioning.

I assume you were expecting Intellisense to tell you what appeared after the first period. Continuing to press the key after the first one failed to do what you want is just an exercise in futility.
