I currently have MS Office 2007 installed on a Windows 10 PC. I mostly use Outlook 2007 which I've been using since Office 96/97.

However I'm having a few difficulties with Outlook such as crashing or freezing once in a while and the the search functions seems to be broken. Some e-mails the images won't display.

I've been looking at MS Office 2010, 2013 and 2016, but don't really need the additional features and overhead.

System requirements MS Office

2007 - 2GB HD space, 500MHz CPU minimum, 1.4GHz processor recommended for some features, 256MB RAM minimum

2010 - suggested minimum requirements are a 500 MHz processor and 256 MB of RAM.

2013 -

CPU 1 GHz clock speed, IA-32 or x64 architecture with SSE2 support
RAM IA-32 edition: 1 GB x64 edition: 2 GB
Hard disk drive 3.0 GB free disk space
Operating system Windows 7 Windows Server 2008 R2 Windows 8 Windows Server 2012 Windows 8.1 Windows Server 2012 R2 Windows 10

2016 -

• 1 GHz processor.
• 2GB RAM.
• 3 GB of available disk space; better to have some extra space for temp files.
• Screen resolution of a minimum 1280 x 800.
• Windows 7 SP1 or above operating system; Works best on latest operating system according to Microsoft.

I'm wondering if upgrading will solve problems with Outlook and what version runs better under Windows 10?

I think perhaps since I'm running Windows 10 64-bit, I should upgrade to a 64-bit version of MS Office?

Have you tried repairing the Office installation? That said, Office 2007 is no longer supported, so upgrading would probably be a good idea, as in some respects the later versions are significantly better products.

There is generally little reason to use 64-bit Office and, depending what addins you use, potentially good reasons for not doing so. Not all addins are 64-bit compatible and the only real advantage with 64-bit Office is for working with exceptionally large Excel workbooks.

I ended up purchasing a valid copy of Microsoft Office 2016 Pro Plus from a (sealed) Microsoft USB key. Once installed the product validated. I then had the MS Office 2016 was checked out by Microsoft and MS confirmed it was legit as I had purchased it from a eBay seller (~2650+ - 100 percent positive feedback) I just wanted to make certain it was legit copy as there's copies of MS Office being illegally sold on eBay that aren't legit)

First nninstalled all copies of Microsoft Office and then installed Microsoft Office 2016 Pro Plus and now everything is ok.

Note: If you have other versions of Microsoft Office Installation installed on you PC. The Microsoft Office installer won't uninstall them and one or installations may interfere with the current installation. So it's better to uninstall all versions when installing a new version as to have two or more versions installed potentially causes problems.

Whilst Office will allow you to keep your older version (except for Outlook), having multiple versions installed is unlikely to cause any problems. Indeed, developers who support multiple Office versions are likely to need this. IIRC, Charles Kenyon, a regular contributor here, has all versions back to Office 2003 installed.

Yeah I think your right but it was Outlook I was having problems with.

Also I had other problems when 2007 was installed and tried to install a later version. Once activated it kept prompting me to activate. When I selected to activate and enter the activation code it then told me that I had used that activation code the max. number of times.

At the time I didn't have a phone near the computer so could not call ms. So returned the product for a refund.

So I don't know, If your not a developer I think perhaps it's better to uninstall any previous copies of MS Office when installing a new version.

Some people recommend this, i.e. first uninstall any installations. I'm not certain why one would want to run multiple versions however it maybe possible but potentially can cause problems.

Like Charles Kenyon, I've had multiple versions installed in the past, without encountering any significant issues. I've also not known anyone to have reliability issues on that front unless they were trying to upgrade and retain an already-faulty installation (all that may do is compound existing problems).

Yeah, well I don't know. When I first started to use a computer years ago there wasn't very many people using computers and hardly any one actually owned a PC, as the world was being run mainly from mainframes and dumb terminals. I can remember when the general population thought of computers as extensional science similar to astrology.

Alot has changed over the years and things have in many ways become more complicated because of all the new functions, features and the addition of an OS with a GUI. It's possible when upgrading from older to newer versions of software to have compatibility problems related to the version of the OS your running.

Anything is possible, but whether it's probable is another matter entirely. Given how rare it is for people to have compatibility problems as a result of having multiple copies of Office installed, I'd say your concerns are rather overblown.

I've been running MS Office since Office 96/97 and can't remember having any problems with versions since, except for ver. 2007 under Wndows 10. Is one reason why I upgraded to a later version(s) as I noticed some strange behavior from Outllook 2007 under Windows 10.

After the final upgrade to version 2016 I've not had any problems. One earlier version I did have problems with the validation and was required to completely remove this installation as well as the 2007 installation in order to install ver. 2016. It was suggested by several people to completely remove MS Office from my PC before the final installation of ver. 2016.

So I think perhaps most people don't have any problems with MS Office and even running multiple installations. However there are a few people who do, which is not a common occurrence.

When I contacted Microsoft support in order to question the legitimacy of the MS Office purchased from an eBay seller I was told there were many illegitimate copies being sold on eBay.

To check the Office 2016 version installed on my PC they had me download and run a remote program that allows them to take over my PC remotely (after giving them permission). They then perform various tests of the Office installation checking files, etc. MS also checks the validation key code which I provided.

Everything tested ok as one hundred percent legit.

Some people do have problems with MS Office installations. If you sift through some of the forums and the Microsoft website you will find people who have had problems with their installation for one reason or another.

It's often suggested when having problems related to ms office is to completely uninstall. There is a utility program that can be downloaded from microsoft.com that will uninstall all versions of MS Office installed on your PC. There are also instructions on how to manually uninstall MS Office from your PC, completely deleting all traces of it's installation(s).

It's sorta like something doesn't seem like a problem until it actually happens to you, then it becomes a problem.

E.g. my car runs and runs just fine for years, as I maintain it, everything is ok. Until something breaks and becomes problem.

Often, quite inappropriately... You'll not find many recommendations to do that on this or most other forums I support.

No the status quo recommends to repair Microsoft office however there are issues running multiple copies of ms office together that sometimes arise.

Usually recommendations such as to repair office are normally recommended before re-installation, DE-installation of previous versions, etc. but under some circumstances people who work for Microsoft have recommended to un-install same and other versions of ms office before proceeding installing or re-installing the same or newer versions.

I'm don't believe Microsoft employees are being inappropriate when they have at times under certain circumstances recommended uninstall other or all version of Microsoft Office installed on a PC.

If somethings not part of the status quo doesn't mean it doesn't exist.

If you want to install and run more than one version of Office on the same PC, here are some tips to help you avoid most set up errors:

"Install and use different versions of Office on the same PC"

https://support.office.com/en-us/art...7-b78c513788bf

Not being able to run Office 365 (the subscription edition) alongside a single-image installation (e.g. Office 2010) has nothing to do with any imaginary problems arising out of running two versions of Office on the same PC. Uninstalling Office is a last resort for resolving problems that typically have nothing to do with running multiple versions of Office on the same PC. Kindly get your facts straight. Thread closed.
