Unable to reinstall Integration Framework from SOI 3.2 and installer once uninstalled and gives an error "cannot install version over an existing version".


This issue occurs because Installer Anywhere leaves behind certain entries which have to be manually removed.



The appropriate process to uninstall IFW is

-      Uninstall IFW from appwiz.cpl (Uninstall or change a program) or using ‘Uninstall IntegrationServices.exe’ located in ..\CA\SOI\Uninstall IntegrationServices

-      Delete hidden ‘Zero G Registry’ folder from <Drive>:\Program Files (86)

But if in case you have Catalyst container also installed on the same machine then it is not recommended to delete ‘Zero G Registry’ folder as it will impact catalyst container.

In this situation we need to follow steps below:

-      Uninstall IFW using ‘Uninstall IntegrationServices.exe’ located in ..\CA\SOI\Uninstall IntegrationServices.

-      Make sure no ‘Integration Services’ is listed in appwiz.cpl if so uninstall it.

-      Rename SAM registry key to SAM.old if it is present in path HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\CA\SAM

-      Backup ..\Zero G Registry\.com.zerog.registry.xml to some other location

-      Delete the below block of data from ..\Zero G Registry\.com.zerog.registry.xml
