Windows 10: Over-writing a previous instance of Outlook 2003 with 2016

    Over-writing a previous instance of Outlook 2003 with 2016


    When I initially installed Office 2016 I forgot to uninstall Outlook 2003 (32-bit). Although Outlook 2016 worked it used a 32-bit profile. I tried cleaning up by removing Outlook 2003 which was OK but now want to reinstall Outlook 2016 using a 64-bit profile. There is no option in Programs and Features (as there was with Office 2003) to select which component to install or re-install or repair. Well there is a repair but you don't know what it is doing... I don't particularly want to remove everything and re-run the install from scratch. Is there any way at all that I can just remove Outlook 2016 without touching Word Excel Access etc and then re-install it?

    First, a quote from an earlier post of mine in another thread:

    Do you really have a reason to use 64 bit Office ? I mean, "I want a 64 bit Office" is not a good enough reason. Basically, in most cases 64 bit Office is not necessary.

    This quote from https://support.office.com/en-us/art...-6c6f49b8d261:

    Reasons to choose the 64-bit version

    Computers running 64-bit versions of Windows generally have more resources such as processing power and memory, than their 32-bit predecessors. Also, 64-bit applications can access more memory than 32-bit applications (up to 18.4 million Petabytes). Therefore, if your scenarios include large files and/or working with large data sets and your computer is running 64-bit version of Windows, 64-bit is the right choice when:
    • You’re working with large data sets, like enterprise-scale Excel workbooks with complex calculations, many pivot tables, data connections to external databases, Power Pivot, 3D Map, Power View, or Get & Transform. The 64-bit version of Office may perform better in these cases. See, Excel specifications and limits, Data Model specification and limits, and Memory usage in the 32-bit edition of Excel.
    • You’re working with extremely large pictures, videos, or animations in PowerPoint. The 64-bit version of Office may be better suited to handle these complex slide decks.
    • You’re working with files over 2 GB in Project, especially if the project has many sub-projects.
    • You’re developing in-house Office solutions like add-ins or document-level customization. Using the 64-bit version of Office lets you deliver a 64-bit version of those solutions as well as a 32-bit version. In-house Office solution developers should have access to the 64-bit Office 2016 for testing and updating these solutions.
    Personally I have never seen a reason to use 64 bit Office. I am quite an experienced Office user, always installing the 32 bit version, regardless of my PC / Windows architecture.
    Having said that, if you want to proceed, you must completely uninstall 32 bit Office before installing 64 bit version. To remove 32 bit Office, use Microsoft's Easy Fix tool, download it here: Uninstall Office from a PC - Office Support

    Hi Kari - Your point is well-made. I was being simplistic in my explanation - I have completed removed Outlook 2003 (there is no longer a "Mail" icon in the Control Panel) but there is a "Mail Outlook 2016 (32-bit)" icon. I use a product called MDaemon which is an Exchange-Lookalike which depends on a client program called "Outlook Connector" installed locally. This permits linking up to the "MDaemon" server. There is a 32-bit and a 64-bit version. The 32-bit version doesn't appear to sit comfortably in a 64-bit environment. I've uninstalled it successfully but the 64-bit version won't install as there must be a vestige of the 32-bit somewhere... It is for this reason that I wanted to uninstall Outlook 2016 , reboot and then reinstall it. But there doesn't seem to be an option in Control Panel "Programs and Settings" to just uninstall Outlook it is either all or nothing and I don't really want to go through the whole process again - this explains the back ground to my question.

    As I mentioned, you must completely remove / uninstall 32 bit version before installing 64 version.

    Well to end this dead-end (not because of anything you said) let me tell you what happened today. After failed efforts to install the "correct" Outlook Client (usual gazillion error messages) I then created a new profile (still with the 32-bit Outlook 2016 Mail Profile icon) and without any explanation it all started working... I went back to what I thought was the corrupt mail profile and reintegrated the email account that was giving difficulties and it all works... I even wound up Internet Explorer and imported the self-signed certificate (which you can't do with Edge) so I am a happy man now. Thanks for taking the time to guide me. Jean

    And that includes the Office Compatibility Pack that works with Office 2000 up to Office 2007 if you have it. Also be sure there's no Viewer installed, such as PowerPoint Viewer, Excel Viewer, Word Viewer [they are being discontinued anyway]. I ran into those issues with the April updates today, hadn't realized the 2 apps had been installed after the 2/2018 updates. There was no reason given for the failure of Windows Update in Settings but found out when trying to do a Repair of Office.

    That's why I recommended OP to use Microsoft's tool to completely remove Office before reinstalling. It removes all traces of Office.

    Right, but the 2 programs that gave me the problem are separate entries from Microsoft Office in Apps/Programs and Features.
