I did create a response transform and changed only the installation path.
Quick divergence - the application is Symantec Nortan Antivirus Corporate Edition client.
Back to what I did. Once the wizard was complete, I went to the validation object to verify that the original .msi was OK. The validation gave me 1 error and 7 warnings. The error was ICE03 Invalid format string. The warnings were errors ICE46 (3), ICE66 (2), and ICE86 (2). I have used Tuner 1.0 in the past so I didn't think anything of these errors.
Next I checked the installation path. Previously this is where I would change the path. It was still showing the INSTALLDIR variable with the default location. I would have thought that the wizard would have changed this. It didn't, so I did. The new location is C:\OSTools\NAV.
I then ran the post validation and received the same errors/warnings. Lastly I built the package using the setup options with the /q for a quiet installation.
The package did install without showing any dialog boxes so something worked. I also tried a command line installation calling the .mst directly.
Help.... 😞
