Outlook addin not working in all XP machines

[optimist_t]

Hi,

I have an outlook addin (DLL and exe) which is developed using VC++ in .NET
framework. After the initial release I made some changes to the application
and the new DLL is put in all users machines. Problem is everything works
just fine in my machine where it is developed and compiled but behaves in a
weird fashion in other machines. I am sure from the changes that it's showing
up the latest DLL but doesn't work as expected. Are there some known problems
with outllok addin for XP machines and what are he resolutions for them?

Thanks,
Trupti
