Issue
Removing software from a PC may leave behind unused / old registry entries and folders from the removed software, this in some cases may prevent software re-installation

Environment
All supported Operating Systems
Cause
This is due to the windows uninstall program not fully removing all elements for the software. Some of this is due to windows thinking the the software may have been removed unintentionally and therefor all the previous settings will still be saved in case of re-installation. For example, when SQL is uninstalled the program folders that contain the database will remain intact.
This may be an issue if, for example, the software is removed due to a problem with the original installation. This is when a complete removal off all components and registry entries may be needed.
Resolution
The best solution for removing all the unused registry entries is to use a program designed to remove obsolete registry entries and temporary files. Some examples of these are:
- CCleaner, which will allow you to clean up your PC by removing past installation components.
- Revo Uninstaller which is useful for removing redundant folders / files / Registry entries.
It may be useful to use both of these programs to ensure a complete cleanup. Revo Uninstaller can be used to remove unused software and then CCleaner to get rid of all the Temp files etc.
Finally remove the relevant folders from within the windows explorer, Example: C:\Program Files (x86)\Continuum
Once done you should then be able to install a fresh clean copy of the application software.
This solution is current in all versions of Windows including windows 10
