How to detect installed version of MS-Office

Question

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

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.

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

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

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

How about HKEY CLASSES ROOT Word Application CurVer

User · Answer

One way to check for the installed Office version would be to check the InstallRoot registry keys for the Office applications of interest   For example  if you would like to check whether Word 2007 is installed you should check for the presence of the following Registry key   HKLM Software Microsoft Office 12 0 Word InstallRoot  Path   This entry contains the path to the executable   Replace 12 0  for Office 2007  with the corresponding version number    Office 97   -  7 0 Office 98   -  8 0 Office 2000 -  9 0 Office XP   - 10 0 Office 2003 - 11 0 Office 2007 - 12 0 Office 2010 - 14 0  sic   Office 2013 - 15 0 Office 2016 - 16 0 Office 2019 - 16 0  sic     The other applications have similar keys   HKLM Software Microsoft Office 12 0 Excel InstallRoot  Path HKLM Software Microsoft Office 12 0 PowerPoint InstallRoot  Path   Or you can check the common root path of all applications   HKLM Software Microsoft Office 12 0 Common InstallRoot  Path   Another option  without using specific Registry keys would be to query the MSI database using the MSIEnumProducts API as described here   As an aside  parallel installations of different Office versions are not officially supported by Microsoft  They do somewhat work  but you might get undesired effects and inconsistencies    Update  Office 2019 and Office 365  As of Office 2019  MSI-based setup are no longer available  Click-To-Run is the only way to deploy Office now  Together with this change towards the regularly updated Office 365  also the major minor version numbers of Office are no longer updated  at least for the time being   That means that     even for Office 2019     the value used in Registry keys and the value returned by Application Version  e g  in Word  still is 16 0   For the time being  there is no documented way to distinguish the Office 2016 from Office 2019  A clue might be the file version of the winword exe  however  this version is also incremented for patched Office 2016 versions  see the comment by  antonio below    If you need to distinguish somehow between Office versions  e g  to make sure that a certain feature is present or that a minimum version of Office is installed  probably the best way it to look at the file version of one of the main Office applications      Using the file path to winword exe    Retrieve the path e g  from the InstallRoot Registry key var fileVersionInfo   FileVersionInfo GetVersionInfo   C  Program Files  x86  Microsoft Office root Office16 WINWORD EXE    var version   new Version fileVersionInfo FileVersion       On a running instance using the  Process  class var process   Process GetProcessesByName  winword   First    string fileVersionInfo   process MainModule FileVersionInfo FileVersion  var version   Version fileVersionInfo     The file version of Office 2019 is 16 0 10730 20102  so if you see anything greater than that you are dealing with Office 2019 or a current Office 365 version

To whoever it might concern  here s my version that checks for Office 95-2019  amp  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  from winreg import   from typing import Tuple  Optional  List    Let s make sure the dictionnary goes from most recent to oldest KNOWN VERSIONS          16 0    2016 2019 O365        15 0    2013        14 0    2010        12 0    2007        11 0    2003        10 0    2002        9 0    2000        8 0    97        7 0    95       def get value hive  int  key  str  value  Optional str   arch  int   0  -
