How To: Upgrade To Office 2010

Advertisement

First go ahead and grab a free copy of Office 2010 beta which will expire in October, 2010. Assuming you have Office 2007 installed, we will discuss two points in this post:

  • Upgrade To Office 2010 Without Overwriting Office 2007
  • Completely Upgrade To Office 2010

Before we begin, please note that all Office apps can co-exist with each other except Outlook and SharePoint Workspace(formerly known as Office Groove 2007). Both these applications cannot co-exist with previous versions so you will need to select one version of the program to have installed on your computer. This is mentioned in Microsoft Office FAQ.

Upgrade To Office 2010 Without Overwriting Office 2007

You might want to upgrade to Office 2010 without overwriting Office 2007 if you are giving beta version a shot. Who knows you may or may not like Office 2010? If you do not like Office 2010, you can simply uninstall it and continue using Office 2007.

Note: If you want to permanently upgrade to Office 2010, skip this part and head straight to ‘Completely Upgrade To Office 2010’.

After you have entered the serial key and accepted the terms, click Customize on the main window.

Office 2010 Upgrade

In the next step select ‘Keep all previous versions’ and go to Installation Options tab.

Keep Office 2007

Now select the Microsoft Office 2010 Applications that you want to install and hit Install Now button.

Completely Upgrade To Office 2010

This step is so easy that even a 5 yr old can figure it out, but I will mention it anyway. When you see the main installation screen, hit the Upgrade button and you are done. This will remove all previous versions of Office 2007 and replace them with Office 2010.

Note: When previous versions of Office 2007 is removed the settings are not deleted. In other words, when you upgrade to Office 2010 all settings and files remain intact.

Bonus Tip: If you want to keep Word 2007 along with Word 2010 and replace all other Office 2007 applications with that of Office 2010 then you need to click Customize and select ‘Remove only the following applications’, finally uncheck Microsoft Office Word and hit Install Now.

Keep Office 2007 2

You can also go to Installation Options tab and select which applications you want to install.

Sadly, users who are using Office 2003 or previous versions will have to perform a clean install of Office 2010. You can always backup your data and import them to Outlook 2010, so that all settings and data are not lost.

    Going back to Office 2007 is not without problems if you've been using Outlook 2010. Outlook 2010 updates the profile, Outlook 2007 cannot handle this. In the end I had to uninstall/reinstall Office 2007 to get everything to work again – maybe I could have repaired it in some way but after trying several alternatives I gave up and reinstalled. Office 2010 is nice but it's a beta and not everything works.

  • Nakodari

    I think you should have installed Office 2010 alongside Office 2007, in this way if you uninstall Office 2010, nothing will happen to Office 2007 except Outloook and SharePoint.

    It is better not to replace Outlook 2010 with Outlook 2007 unless you are 100% sure.

  • CalleJ

    That is what I did – I kept Office 2007 and installed 2010 with the “keep previous..” option. But you cannot switch back and forth between the two, but I guess that if you do not upgrade you Outlook-profile (I cannot remember if that was an option) going back to 2007 will be easier.
    Anyway – I´ll stick to 2007 for now on my production PC, will maybe install 2010 on a test pc – and I'll definately get 2010 when it's ready

    it seems that we cannot keep the existing version of Outlook if we install Outlook 2010.

    Moreover, it is possible to let coexist Office 2003 and Office 2010 (the profile is created every time you launch each ones but “it is possible”; except for Outlook again)

  • Sunny

    I didn't like Office 2010 beta so I thought I could just uninstall it and return to Office 2007. Office 2007 seems to have disappeared along with it. I didn't know about the keep previous versions option until I read your post just now. I'm guessing that what I did was upgrade to 2010 beta “completely”. There was no “installation options” tab when I was installing. I'm not very savvy, but not stupid either. If such an option had presented itself, I would have known better than to completely override Office 2007. Perhaps because I installed the “professional” version?

    Anyway, since I have lost the installation CD and product key to reinstall 2007, does this mean all is lost? Is there anything I can do?

  • Mike

    So far it looks like installing Outlook 2010 will kill the 2007 Outlook install. I don't ever replace a working software with a Beta of anything. After choosing to keep 2007 and install 2010, all 2007 apps (except for Outlook – Outlook is gone) try to install again when starting them is attempted. So instead of two versions of Office, I now effectively have none. If I figure out a fix I'll post it.

  • after installing office 2010 I lost outlook 2003. Everything else is fine, but I really want outlook 2003 back. Mainly in case anything goes wrong with office 2010 I still have a working version of outlook.

    Everything else is fine, its just outlook 2003 that has vanished from my system. Any ideas?

  • aki kyriakou

    I am currently using office 07. I have a full version of office 10. What i am worried is that i don’t want to lose any of my information/emails/contacts etc from outlook. How can i go about installing the new office 10 on top of the 07 and not lose any of this info.

    You help will be greatly appreciated and a big sigh of relief.

    Many thanks
    Aki.

    Whilst upgrading to office 2010 from office 2007 I have los alll f mok rsnal foldehow can recover these?

  • Mike Fluckiger

    I upgraded from Outlook 2003 to Outlook 2010 a month ago. The junk filter lists are intact and did not change but now many emails from contacts and people on the safe senders list go to junk? Really frustrating. Does anyone have any suggestions? Perhaps deleting all safe senders, safe recipients and blocked senders and starting from scratch?

    Any suggestions will be appreciated.

    Thanks,

    Mike

  • Dan

    So how do I now contact my former Groove buddies that have not upgraded to 2010 with Sharepoint.

    • Jonathan

      I want to iinstall Office 2010 to upgrade and replace 2003 but obviously be able to access all the 2003 documents from all the Office products in Office 2010, including Outlook 2003 with contacts and calendars. Is this a staight upgrade to 2010, conversion automatic?

      Thank you

  • Tabishsunset

    MS Office 2003 upgrade to MS Office 2010 is possible.
    Dears. I have read many article about upgrading office 2003 and 2007 and they all say that it is not possible to updrade office 2003 to office 2010. I say that is not true. I am using office 2003 pro+SP3. I could easily upgrade office 2003 to office 2010 while keeping the user profile.
    The step were the same as shown above.
    1-Run the setup.exe from the office 2010 installation source.
    2-Click on the upgrade button.

    It is done. The outlook profile and the rest are moved to the office 2010.

    Success people.

    • Joel

      Tabishsunset,
      Are you saying that the upgrade from 2003 to 2010 will transfer all the Outlook folders, contacts, emails, everything I would need? Thanks

  • Jack Hoover

    I just installed Office 2010 and then realised my Outlook (2003) sudenly disappeared with all important emails, contacts etc. Conclusion? Never ever use any Microsoft shit again.
    I will return this crap back to shop with lots of compliments and this week task will be to find better alternative for Outlook. I already have Open Office which is better in every way than MS Office, so that is not a problem.

  • I am impressed with the blog writer. The author really needs an appreciation. Amazing work. Keep it up.

      Hi All….

      Can I upgrade MSo 2003 to 2010? and if i am doing so may i have to purchase separate key? plz suggest me..

      • MGKimmel

        Yes, you can upgrade, but you will also need to purchase a new key. My opinion (for what it’s worth) is to avoid upgrades whenever possible. Since you will have to purchase a new license anyway, I would recommend just purchasing the full 2010 (or 2013 OR consider Office 365) and do a full, clean, new install.
