SaveFileDialog not getting opened in VS2010

Question

I have created an application in visual studio 2010 using C#.net. In that application I am generating MS-Word report... For that I have used SaveFileDialog for saving that documnet to a particular location.. Initally it was woking fine...But from some days my SaveFileDialog window is not getting opened on my system.
Same code is working on other machines without any problem.
Things I have done to fix this problem :

1. Uninstall VS 2010 and reinstall it.
2. Installed VS 2012

But that problem is still there.
P.S. I have Windows 7 O.S. 64-bit

Any help would be appreciated.

If you are calling it from the Main() thread, ensure that Main() is marked with the [STAThread] attribute like this:

[STAThread]
private static void Main()
