Welcome to the forums!
 
 In general, unless you got the same problem, it'll probably be better to start a new thread for your question. Anyhow, I take it you already tried the .NET framework? What version of Windows do you have?

 Thank you, Star Admiral for your kind welcome and guidance.
 
 So, my issue concerns all the obvious facts why a program wouldn't work being eliminated. That means, I have ruled out .NET framework(I have 1.1 sp1, 2.0 sp2, 3.0 sp2, 3.5 sp1). My windows is xp pro sp3. 
 
 Ideas are appreciated, thanks.
