One of my requirements is to delete the installed files if a user presses Cancel during a ComponentMoveData. How can I do this? When Cancel is pressed in my InstallShield, the subset of the files remain.

I suspect I'm missing something in logging? Here is my code:

nResult = ComponentMoveData( MEDIA, nDisk, 0 );
svLogFile = UNINST_LOGFILE_NAME;
nStartResult = DeinstallStart(TARGETDIR, svLogFile, @UNINST_KEY, 0 );

Thanks very much, I appreciate anyone's help on this issue.

Move to an MSI-based installation package that has true rollback support.

Yes, that is true: provided you don't make any system changes before InstallInitialize or after InstallFinalize in the execute sequence. The system change transaction runs between these actions.

If you stay with InstallScript: make sure you start the logging (DeinstallStart) before your start the file copy (ComponentMoveData)

Thanks for the replys. Altho I started my logging earlier as suggested, when I click on Cancel on the FILE COPY diaglog, the I.S. just ends without deleting the files that it has copied to the machine.

Is there a way to trap that Cancel right before the program bugs out? If I could, then I could write a command in the setup.rul to just delete the folder on the way out. How do I get control after that Cancel (and cancel confirm) is chosen?

Thanks.
