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. 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 is installed you should check for the presence of the following Registry key:. 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.

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.
You cannot distinguish among the three , , O , 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. Case 3 : if the computer has Office installed, there is a value called obussinessretail 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 Then I enumerate LicensingNext and try to see if any name has a prefix o , if it finds it then its O If it does not, then its Office Frankly speaking, I did not have enough time to test the logic under varying environment.
So please, note that. There you get path to executable and check version of that file. I figured out an elegant way to detect the “Microsoft Office Version” that perhaps also works, when you want to detect if you have “Office ” or “Office ” installed. I just detected the installation path of “Microsoft Office” then declared a System. The infos stored in “OfficeVersionInfo” in the code example are the infos you get when you rightclick on the “winword.
See this: Details of winword. 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.

This is my favorite as it avoids the Wow64 issue, and also supports the case where multiple office versions are installed and if so I believe CurVer is set to the the last version launched. Wish I saw this earlier, works a treat in Inno Setup as well.
This is a good answer, but for clarity, it only gets the internal version, e. It does not return file or registry paths. You still have to get that separately. Word also show Word.

Net was installed or if a partial install of Office was done instead of a complete install. This is perhaps most typical for partial installs of only Outlook – the corresponding Microsoft.
Outlook dll is typically not installed until the user downloads and installs the “Primary Interop Assembly” for Outlook. The other very minor problem is that the “default” clause on the “switch” statement is saying “Too Old!
A more likely cause of that code being executed is that the version of Word or whatever is too new. This was in fact illustrated by the update made to this program to handle Office – before that update was applied the previous version of this program was saying that Office was too old! Does this code fails if Office not installed in machine?
So, my logic follows below: Case 1 : If the computer has the MSOffice installed, there is no subkeys under Licensing.
