Office installed with Click-to-Run and Windows Installer on same computer isn’t supported

Click-to-Run is the technology used to install Microsoft 365 subscription and most versions of Office 2013 and newer. Windows Installer technology (MSI) was used to install the volume license editions of older versions of Office 2016 and older, such as Microsoft Office Professional Plus and Microsoft Office Standard.

You can’t install the same version of Office products that use two different installation technologies installed on the same computer. This also applies to standalone applications like Access, Visio, Project, Skype for Business, or OneDrive for Business.

You’ll get the following error message if Office detects this incompatibility:

Note: In some cases, you also can’t have two different versions of Click-to-Run applications on the same computer. For more information, see «Stop, you should wait to install Office 2016» error.

What can I do about this error?

Uninstall the Windows Installer (MSI) version of Office

You can stay with the Windows Installer version of Office and not install the Microsoft 365 Click-to-Run version you were trying to install. Or, do the following:

Follow the steps in Uninstall Office from a Windows computer to remove the Windows Installer version of Office.

Retry the installation of Office you were doing when you got the error message.

For volume license versions of Project or Visio, use the Office Deployment Tool (ODT) to install a Click-to-Run version

If you have a volume license for Project 2016 or Visio 2016 and you’re trying to install the Click-to-Run version of Microsoft 365 Apps for enterprise, you can use the Office Deployment Tool to download and install the Click-to-Run perpetual (stand-alone) versions of Project 2016 or Visio 2016. See Use the Office Deployment Tool to install volume licensed editions of Visio and Project.

We’re working to fix the issues that may come up when using Office with Windows 10. In the meantime, please use the following workarounds to fix the problems.

Need more help?
If these workarounds don’t resolve your problem, use the options at the bottom of this page for support.

Common issues

Office documents open slower after Windows 10 Fall Creators Update

In Windows 10 Fall Creators Update, the active Antivirus product can dynamically scan Office documents via the Antivirus API for Office when you open them. This helps the active Antivirus product to detect malicious documents that obfuscate malicious content by employing techniques like document encryption. This scanning occurs with all versions of Office documents and could result in a delay of up to 1 second per document.

Microsoft is investigating this issue and will post an update here once the issue is resolved. For more information on this new behavior, see Introduction to the Antivirus API Reference for Office.

Windows screen is flickering or flashing after logging in

You might see a flickering screen if you’re running Microsoft 365, or Office 2016 build 16.0.7668.2066, which was released to a small group of customers between 1/25 and 1/30. As of 1/31, Microsoft 365 or Office 2016 build 16.0.7668.2074 is available and contains a fix.

To resolve this issue, please update Office to the newest version. Since the screen is flashing, you will need to do this using a command line. Please see this article for step by step instructions: Windows screen is flickering or flashing after logging in.

You can’t find Office applications after Windows 10 upgrade

Windows 10 doesn’t pin the Office apps to the Start menu or the Taskbar by default, but there are a few ways to find and open Office applications from the Start screen and taskbar in Windows 10.

How to upgrade to Windows 10 on new devices that include Microsoft 365

If you just purchased a new device that includes Microsoft 365, we recommend installing Office before upgrading to Windows 10.

You can’t print after upgrading to Windows 10

You may need to install new drivers for your printer. Also try running the printing troubleshooter to fix the issue.

You need help with licensing or product activation

After upgrading to Windows 10, Office apps display very large or very small on your monitor, or you have blurry text in your Office applications.

Error messages

You get an error when opening Office 2013 documents after upgrading from Windows 7 to Windows 10, such as Word experienced an error trying to open the file or This file is corrupt and cannot be opened.

To resolve this issue, start one of your Office 2013 applications, like Word, and then select File > Account > Update Options > Update Now to install the latest updates.

Outlook issues

After installing the Windows 10 Anniversary update, dragging emails to the file system or between folders does not work.

The issue affects all supported versions of Outlook 2010, 2013, and 2016. It may also happen with Mozilla Thunderbird.

Our engineering teams have investigated this issue, and are planning to release a fix in the near future. We’ll post back here when we have more information.

After installing Windows 10, Business Contact Manager (BCM) may crash due to chart control issues during .Net registration.

BCM depends on the .NET framework for some of its features.

When you click a hyperlink to a Web page in Outlook 2010 or Outlook 2007, you’re prompted to specify Internet Explorer 11 as default browser.

The Office offline installer may help bypass potential proxy, firewall, antivirus, or Internet connection issues that might occur during an Office installation.

For steps to install an offline version of Office, see Use the Office offline installer and select the correct tab for your version of Office.

You can’t install Access

If you can’t find Access on your computer even though its included with your Office 365 subscription, try the following in the order listed.

Note: Access can only be installed on computers running Windows 7 or later. You can’t install Access on a Mac.

Open an Office application, such as Word or Excel and create a new document.

From the ribbon, select File > Account.

Under the Product Information section, select Update Options > Update Now.

When the update is complete, click Start and look for Access in your list of apps.

Follow the steps in Install Office on your PC or Mac. If you need to install the 64-bit version, select the PC step-by-step tab and expand the section, «Install or reinstall an Office for business product.»

You don’t see an option to install Office, check if you have a license

If you’re not already signed in, go to http://admin.microsoft.com and sign in with your work or school account.

Note: If you’re unable to sign in with your work or school account, you may be signing in to the wrong Office 365 service, see Where to sign in to Office 365.

From the browser header, go to Settings > My app settings > Office 365.

On the My account page, select Subscriptions.

You’ll see the services that you’re licensed to use, such as the latest desktop version of Office, SharePoint Online or OneDrive for Business, and Exchange Online. If you don’t see The latest desktop version of Office in the list (or Project or Visio if your organization has a plan that includes those applications) your admin probably hasn’t assigned an Office license to you. If you’re an admin, see Assign licenses to users in Office 365 for business. For more information, see What Office 365 business product or license do I have?

Not all Office 365 subscription plans come with the fully installed Office applications. See the bottom of the Office for business column for a list of plans that don’t include the Office desktop client. If your organization has one of these Microsoft 365 plans, the Office 365 admin can switch to a different Office 365 plan or subscription or buy another Office 365 for business subscription for users in an organization who require the full version of Office.

If you’re an admin and you aren’t sure what plan you have, follow the steps in What Office 365 for business subscription do I have? For a comparison of plans, see compare small business plans or compare enterprise plans.
