So, recently we noticed that the installer doesn't uninstall from the Control Panel by using 'Uninstall/Change' option.
It works fine by right-clicking on the .msi and selecting 'Uninstall' and also by running it from the command-line. When looking at the log, it says it was 'reconfigured' rather than uninstalled.
I will send the verbose log and the .aip to the support email.
Thanks,
Bryan
