In some scenarios, depending on the Windows Server version, you’ll also need to add the IUSR and IUSR_ accounts. Go to the Security tab, where you’ll find three group boxes: for the first two of them – Launch and Activation Permissions and Access Authorization – select the Customize radio button, then add the same identity that runs your web site’s Application Pool – the one which you took note of few minutes ago.Select This User, then put the credentials of the account who installed MS Office – or an administrative account. Go to the Identity tab, where you’ll see three radio buttons: The Interactive User, The Launching User and This User.Right-click the entry and select Properties:.For additional info on that topic, read this StackOverflow thread.ĭcomcnfg command from Windows > Start > Run or from a command-prompt: go to Component Services > Computers > My Computer > DCOM Config, then locate the various “ Microsoft XYZ Document” and/or “ Microsoft XYZ Application” entries, where XYZ are Word, Excel and/or Access – depending on what you need to access programmatically from your ASP.NET web application: you’ll need to perform the following tasks for each one of them. If that’s too much for you to handle, you can change the identity to a “static” account… but you shouldn’t do that, as the ApplicationPoolIdentity usage is a best practice to deal with IIS7+ / IIS8+ Application Pools in a secure way.

If you fond the ApplicationPoolIdentity there, you need to do some little extra-work: as you might know, that user it’s a dynamically created, unprivileged account: to change its permissions in the following steps, you’ll need to look-up for the IIS AppPool\ role. Keep a note of that user (or system) account, because you’ll need it later on.

We won’t expand such topic here any further, but you can see a sample lockers implementation / tutorial / code sample in this post. TryEnter or other similar methods to synchronize access to these kind of calls. Yeah, that’s about it! I f you thought that you could avoid installing it, you were wrong: a locally-installed instance of Microsoft Office is required to use the libraries, because they basically launch the actual MS Office apps in background to handle the calls.Īs a matter of fact, they also do that in an highly-inefficient way, often messing up with the multi-thread context of a typical Web Application – that’s why you should use lock, Monitor. If you’re hitting the 80040154 Class not registered error, it probably just means that Microsoft Office isn’t installed on your IIS server machine. These are the most common errors you might encounter when dealing with : luckily enough, there’s a quick solution for each one of them. (0x800A03EC): Microsoft Office Excel cannot access the file (0x800706BA): The RPC server is unavailable.

However, when you’ll eventually want to publish your efforts in a production server (Windows Server + IIS), you might deal with one of the following errors:

In case you also need a tutorial / coding sample about how to implement library set in a typical ASP.NET C# application, we suggest to read this post: here we’ll take for granted that you’ve already did something like that and you’re trying to publish it onto a production IIS server machine – arguably, without success.Īs soon as you install these assemblies in your developer machine you’ll be able to deal with the Office files without issues. This is a neat collection of libraries, released by Microsoft through NuGet, which can be used to programmatically access – open, edit, save, create and so on – Microsoft Office files such as: xls / xlsx (Excel), doc / docx (Word), mdb (Access) and so on. If you’ve stumbled upon this post you’re most likely dealing with the Microsoft Office primary interop assemblies (PIAs), also known as library set.
