Sitecore installation name is not a unique error

I tried to configure an instance of Sitecore dev, and I accidentally set the wrong path. It seemed like the easiest way to fix this was to remove the IIS instance and delete the Sitecore database.

Unfortunately, now I get an error message when I try to remove ("The error caused the Sitecore Installation Wizard to terminate prematurely") and the "not unique name" error occurred while trying to install a new instance. What do I need to do to allow me to use the same instance name again?

So, @OptimizedQuery delivered me most of the time until the Windows uninstaller stopped working. Then I went into the registry and found the corresponding entries here [HKEY_LOCAL_MACHINE\SOFTWARE\Sitecore CMS].

So here is a list of steps.

  • Try the Sitecore installer and choose to remove the corrupted instance.
  • If this fails, manually remove it from IIS and delete the databases before using the uninstaller in the application Programs and Features.
  • If this fails, use regeditand remove the appropriate child elements [HKEY_LOCAL_MACHINE\SOFTWARE\Sitecore CMS]. Be sure to delete only the one that has the corresponding key InstanceName.

Try uninstalling this Sitecore instance using the Windows Programs and Features dialog box in Control Panel.

@cwallenpoole . Sitecore , :

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Sitecore CMS]

, :

  • try uninstalling using the sitecore installer and select the instance to uninstall
  • try deleting the Control Panel> Programs and Features form, and then select the instance to remove or delete.
  • If the above steps failed, go to regristry and select the path [HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Sitecore CMS] and then select the instance to delete

Hope this will work in most cases. if you find more steps add them :) happy uninstalling!
