在这篇文章中，我们将概述一些提示，以帮助您避免大多数Office 设置或安装错误，如果您想在同一台Windows 10 PC上安装和运行多个版本的Office 。这适用于Office 2019、Office 2016、Office 2013，如果没有另外说明，以下声明也适用于Visio和Project等单个应用程序。

请记住，即使您遵循以下建议，当您在同一台 PC 上使用两个版本的Office时，您仍可能会遇到问题。^(Office)如果您决定不保留这两个版本并卸载早期版本，您可能需要修复剩余的 Office 套件版本，以确保文件关联能够正常工作。

^(Install)在同一台计算机上安装和使用不同版本的Office

提示/建议如下但不限于：

1]如果您有Office 365订阅或非订阅版本，例如Office Home and Business 2019、2016^{(Business 2019)}或 2013，在大多数情况下，您无法在同一台计算机上同时运行这些版本。

对此有一个例外：如果通过MSI安装两个产品之一（这对于批量许可产品很常见），则这两个产品可以并行运行。

2]您可能会看到停止，您应该等待安装 Office^{(Stop, you should wait to install Office)(Stop, you should wait to install Office)}错误。如果您的计算机上安装了独立的Office应用程序（例如Word），但您尝试安装的套件中已包含该应用程序的较新版本，则可能会发生这种情况。在这种情况下，独立版本将被删除。

但是，如果独立应用程序不是您尝试安装的新Office套件的一部分，则独立应用程序将保留在计算机上，并且Office套件将成功安装。

3]不支持在启用远程桌面服务^{(Remote Desktop Services)}( RDS )时在Windows 10上运行多个版本的Office 。

On a computer with Remote Desktop Service (RDS) enabled, it is possible to install multiple versions of Office. However, this is not a supported Office configuration. To get the computer into a supported configuration, you can either disable RDS or you can uninstall versions of Office, leaving only one version installed.

4]首先^(4]) 安装^(Install)早期版本的Office。例如，在安装Office 2019、Office 2016或Office 2013之前安装Office 2010。这也适用于Office系列的其他产品，例如Visio、Project或Access Runtime以及语言包^(Packs)和校对工具^{(Proofing Tools)}。如果您不按此顺序安装Office，您可能必须在之后修复更高版本的Office。

5] 确保^(Make)所有版本的Office都是 32 位或 64 位。你不能两者兼而有之。尝试安装 Office（64 位或 32 位）时，您可能会看到无法安装^{(Office (64-bit or 32-bit) couldn’t be installed)}错误。

要修复此错误并从 32 位切换到 64 位（反之亦然），您必须按此顺序执行以下操作。

• 卸载 Office
• 安装 32 位或 64 位版本的Office。

How to install different versions of Office on the same Windows 10 PC

In this post, we will outline some tips to help you avoid most Office set up or installation errors if you want to install and run more than one version of Officе on the same Windows 10 PC. This applies to Оffice 2019, Office 2016, Office 2013 and if not otherwise stated, the following statements also apply to individual apps such as Visіo and Project.

Keep in mind that even if you follow the recommendations below, you might still run into issues when you use two versions of Office on the same PC. If you decide not to keep both versions and you uninstall the earlier version, you might need to repair the Office suite version remaining to make sure that the file associations will work correctly.

Install & use different versions of Office on the same computer

The tips/recommendations are as follows but not limited to:

1] If you have an Office 365 subscription or non-subscription versions such as Office Home and Business 2019, 2016 or 2013, in most cases you can’t run these versions together on the same computer.

There is one exception to this: If one of the two products is installed through MSI (which is common for volume licensed products), these two can run side-by-side.

2] You may see a Stop, you should wait to install Office error. This can happen if you have a standalone Office application (such as Word) installed on your computer, but a newer version of the application is already included in the suite you’re trying to install. In this case, the standalone version will be removed.

However, if the standalone application isn’t part of the new Office suite you are trying to install, then the standalone application will be left on the machine and the Office suite will successfully install.

3] Running multiple versions of Office on Windows 10 when Remote Desktop Services (RDS) is enabled is not supported.

On a computer with Remote Desktop Service (RDS) enabled, it is possible to install multiple versions of Office. However, this is not a supported Office configuration. To get the computer into a supported configuration, you can either disable RDS or you can uninstall versions of Office, leaving only one version installed.

4] Install earlier versions of Office first. For example, install Office 2010 before installing Office 2019, Office 2016, or Office 2013. This also applies to other products from the Office family, like Visio, Project or Access Runtime as well as Language Packs and Proofing Tools. If you don’t install Office in this order, you may have to repair the later versions of Office afterward.

5] Make sure all versions of Office are either 32-bit or 64-bit. You can’t have a mix of both. You may see Office (64-bit or 32-bit) couldn’t be installed error when trying to install them.

To fix this error and switch from 32-bit to 64-bit (or vice-versa), you must do the following in this order.

• Uninstall Office
• Install the 32-bit or 64-bit version of Office.
