"Cannot Create This File When This File Already Exists" Installation problem

Hi;

I created a web setup project that will be replace some files and folders in a specific folder under wwwroot...

when I ran this setup pack(on windows server 2003 sp2), I got this error message:

"Cannot Create This File When This File Already Exists"

before doing that, I created a simple setup project to replace some files and folders under wwwroot and I ran it on my pc and everything was OK.....

Does anybody have any ideas what could be going on here?

Thanks so much ....

Do you have any custom actions in your setup project?

Yup.....

and in this custom action, I was trying to create a file that is already exits....that's why I got this message...

Thanks for your reply....
