[vb2005] uninstall program shortcut

hi ..
iam almost done with my program,
after adding the setup project, ive noticed that it doesn`t contain an uninstall.exe to uninstall the program, as it was in VB6 ..

iam not sure if iam making something wrony, but i thought i could use this to uninstall my program ..

Code:

---

%windir%\system32\msiexec.exe /x {MY-GUID}

---

but it is not working ..
it says :
This action is only valid for products that are currently installed.

can anyone please help me to add an uninstaller, or if there`s a way to make it using the D&P from VB2005, i would be very grateful ..

thanks in advance

Why not use the Add/Remove programs option in Windows to uninstall the application?

iam just wondering why i cann`t make a shortcut to uninstall the program ..
i can use the add/remove program, but just want to solve this problem now with the uninstall shortcut ..

thanks anyway
