NOTE: This is NOT support and support can not help troubleshoot any problems arising in using this method.
We will require a clean uninstall and reinstall of the application and issues reproduced if there are unexpected issues.
The TDM Portal uses an installer anywhere wrapper.
All this does is call a windows MSI installer to do the actual installation of the individual products or components.
Windows MSI installers store information in two places.
<Product-GUID>} if the installer doesn't need elevation
To prevent the MSI installer from prompting to uninstall, repair, etc and act like it is a new installer the registry key for the installer product must be removed.
This will cause the installer to go through a new installer.
NOTE: This has not been tested for expected outcomes other than starting the installer.
This process is not supported, expected, or designed for.
Support nor dev can provide any insight into what should be considered expected behavior of this operation or change it.
If there are any problems the only solution will be to do a complete uninstall of the product and clean reinstall of the product.
