Does anyone know what would be the best way to detect which version of Office is installed? Plus, if there are multiple versions of Office installed, I'd like to know what versions they are. A bonus would be if I can detect the specific version(s) of Excel that is(/are) installed.
To whoever it might concern, here's my version that checks for Office 95-2019 & O365, both MSI based and ClickAndRun are supported, on both 32 and 64 bit systems (falls back to 32 bits when 64 bit version is not installed).
Written in Python 3.5 but of course you can always use that logic in order to write your own code in another language:

'11.0': '2003',
'10.0': '2002',
'9.0': '2000',
'8.0': '97',
'7.0': '95',
}

Remarks
If you've installed 32-bit Office on a 64-bit machine, you may need to check for the presence of "SOFTWARE\Wow6432Node\Microsoft\Office\12.0\", substituting the 12.0 with the appropriate version. This is certainly the case for Office 2007 installed on 64-bit Windows 7.
Note that Office 2010 (== 14.0) is the first Office for which a 64-bit version exists.
How about HKEY_CLASSES_ROOT\Word.Application\CurVer?
A bonus would be if I can detect the specific version(s) of Excel that is(/are) installed.
I know the question has been asked and answered a long time ago, but this same question has kept me busy until I made this observation:
To get the build number (e.g. 15.0.4569.1506
), probe HKLM\SOFTWARE\Microsoft\Office\[VER]\Common\ProductVersion::LastProduct
, where [VER]
is the major version number (12.0 for Office 2007, 14.0 for Office 2010, 15.0 for Office 2013).
On a 64-bit Windows, you need to insert Wow6432Node
between the SOFTWARE
and Microsoft
crumbs, irrespective of the bitness of the Office installation.
On my machines, this gives the version information of the originally installed version. For Office 2010 for instance, the numbers match the ones listed here, and they differ from the version reported in File > Help
, which reflects patches applied by hotfixes.
Why not check HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\[office.exe]
, where [office.exe]
stands for particular office product exe-filename, e.g. winword.exe
, excel.exe
etc.
There you get path to executable and check version of that file.
How to check version of the file: in C++ / in C#
Any criticism towards such approach?
public string WinWordVersion
{
get
{
string _version = string.Empty;
Word.Application WinWord = new Word.Application();
switch (WinWord.Version.ToString())
{
case "7.0": _version = "95";
break;
case "8.0": _version = "97";
break;
case "9.0": _version = "2000";
break;
case "10.0": _version = "2002";
break;
case "11.0": _version = "2003";
break;
case "12.0": _version = "2007";
break;
case "14.0": _version = "2010";
break;
case "15.0": _version = "2013";
break;
case "16.0": _version = "2016";
break;
default:
break;
}
return WinWord.Caption + " " + _version;
}
}
Despite the fact that this question has been answered long time ago, I found some interesting facts to add that are related to the answers above.
As Dirk mentioned, there seems to be a weird fashion of version control from MS, starting from Office 365 / 2019. You cannot distinguish among the three(2016, 2019, O365), by seeing at the executable paths anymore. And just like he reputed himself, looking at the builds of the executable, as a mean of telling which is what, isn't quite effective either.
After some researching, I found a feasible solution. The solution lies under the registry subkey Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Licensing\LicensingNext
.
So, my logic follows below:
Case 1: If the computer has the MSOffice 2016 installed, there is no subkeys under Licensing
.
Case 2: if the computer has MSOffice 2019 installed, there is the name of the value (which is one of the Office Product ID). (e.g. Standard2019Volume
)
Case 3: if the computer has Office365 installed, there is a value called o365bussinessretail
(which is also a product ID) along with some other values.
The possible productIds are provided here.
To distinguish the three, I just opened the key and see if fails. If the open fails, its Office 2016. Then I enumerate LicensingNext
and try to see if any name has a prefix o365
, if it finds it then its O365. If it does not, then its Office 2019.
Frankly speaking, I did not have enough time to test the logic under varying environment. So please, note that.
Hope this will help whoever's interest.
