The correct procedure to uninstall a Shared Network installation of Progress OpenEdge is through:
Control Panel -> 'Add/Remove Programs' > Uninstall to remove the Shared Network installation
Control Panel > Programs and Features > Uninstall a program to remove the Shared Network installation
If the Uninstall for some reason fails, a re-install of the same software on the client will likely fail. When a reinstall is attempted after a failed uninstall, a message similar to the following will appear:
A previous installation of the same version has been detected. You must uninstall the previous installation before continuing
In order to get around this situation, it is necessary to manually remove the previous installation from the client in order to successfully perform a subsequent NetSetup installation.
If planning to install the same version of the shared installation on the client again, it is not necessary to remove .DLL files that were copied to the client, only the related registry entries. To remove the installation completely, remove the .DLL files were copied onto the client. The following registry keys lists all ocx and dll files and the paths to the file that were installed on the netsetup client PC:
HKEY_LOCAL_MACHINE\SOFTWARE\PSC\SHARED\<version>\SystemDLLs
To remove the references of the previous installation, edit the Windows registry by running regedit.exe and remove the keys that are related to the NetSetup.
