I think i can use orca to fix my problem...i actually have a custom 
action that tries to get a file from the installlocation, and get some 
data from there(while uninstalling)
but i accidentally added that action after the deletefiles action. So i 
can change that with orca.
The problem now is:
I don't have the msi anymore. I have the GUID.
How can i get the msi? as in where does control panel grab it from when 
uninstalling a program?
I am using windows vista
