You are missing Impersonate="no" in your CustomAction element. On Vista, the
action runs impersonating the installing user, who (with UAC turned on) does
not have write permission under Program Files, since it is the user before the
elevation prompt.
If you set Impersonate="no", then the custom action will be called from SYSTEM,
which does have that right.

Hello,
I have custom action in C++ dll that opens installed file and modifies it.
But in Windows Vista if file needs admin rights(for example if file is under
Program Files tree) opening file for writing fails.
I'm trying to use
<CustomAction Id="SettingUpConfigFile" BinaryKey="InstallHelper"
DllEntry="SetUpConfig" Execute='deferred'/>
<Custom Action="SettingUpConfigFile" After="PublishProduct">NOT
Installed</Custom>
Any ideas how to solve this problem?
Thanks for helping,
Benas
