You could use three custom actions: A deferred action that makes a backup copy of the file and then modifies it (basically what you have now). A rollback action that would replace the modified file with the backup copy. A commit action that deletes the backup copy.

A rollback custom action should also handle the case where the deferred custom action is interrupted in the middle of execution. You can do this in WiX by using the following sort of syntax: <InstallExecuteSequence> <Custom Action="appInstallRollback" After="InstallFiles">NOT Installed AND NOT REMOVE</Custom> <Custom Action="appInstall" After="appInstallRollback">NOT Installed AND NOT REMOVE</Custom> </InstallExecuteSequence> <CustomAction Id="appInstall" FileKey="myapp" ExeCommand="/dosomething" Return="check" Execute="deferred"/> <CustomAction Id="appInstallRollback" FileKey="myapp" ExeCommand="/undosomething" Return="check" Execute="rollback"/> On 6/28/06, Kalappa Pattar <[EMAIL PROTECTED]> wrote: Hi All, In my installer, I call utility.exe through VB script. This utility modifies the config file while installing and roll back the changes to config file while un-installing. Now while installing say the event writing to the config file is over and user will cancel the setup after that event. The changes done to the config file won't be rolled back. So how and where to handle rolling back the action of some external exe if the user clicks cancel button after the external exe (which is called through VB script) has performed it's action?
