Here, the environment is that of McAfee Agent (MA) version 4.6 and 4.5. The technical glitch that is discussed here is ‘error 1603’. It is a deadly error that occurs during installation and the software fails to install and/or upgrade, as the case may be. For instance, while performing the update from MA 4.5 to 4.6 the bug may occur.
It is found that both upgrade and installation attempts fail, no matter whether they are attempted by a local or an ePO deployment task. Again, it might be possible for the affected users to manually eradicate the McAfee Agent. However, eradicating the agent does not resolve the tribulation completely and this is due to the reason that subsequent installation attempts also go unsuccessful.
Grounds - The cause is that the odds and ends continue to persist in the registry from older MA installation. The earlier ones prevent the latest releases from getting configured. Furthermore, the MSI internal registry data from the McAfee Agent is absent of sync with the actual release of agent that is being installed.
Solutions – To get over the broken MSI registration for MA, an MSI cleanup application can be brought into use and also that the MA entry must be erased from the MSI database located on the system of the client.
The other way out is to use an escalation tool in particular for removing a broken MSI registration for MA. As the utility erases a wrecked MSI registration, its use must be restricted to computers that are affected with this particular issue only. This tool can be employed for correction and should not be incorporated in the build of MA.
Effective Solution - Nevertheless, the most effective way to do away with the bug and its disastrous effects is to ring McAfee phone number rendered in public interest by SupportBuddy.
