如果您的计算机上安装了Microsoft Office试用版，并且您正尝试安装零售版的另一个实例，则Windows计算机上可能会出现此错误。当您尝试打开Microsoft Office应用程序（如Word、Excel等）时会发生此错误。整个错误消息显示 –此操作仅对当前安装的产品有效。
^{(This action is only valid for products that are currently installed.)}

当已安装的试用版过期时，会出现错误消息或窗口。同时，您安装了另一个Microsoft Office^{(Microsoft Office)}实例并尝试打开Excel、Word等。这会导致Microsoft Office安装过期和新安装之间发生冲突。无论是零售副本，还是您使用在线安装程序或安装离线包，您都可以在Windows计算机上收到相同的错误消息。

任何Microsoft Office^{(Microsoft Office)}版本都可能出现此问题，包括Microsoft Office 2019、Office 365等。

此操作仅对当前安装的产品有效

修复此操作仅对当前在打开^{(This action is only valid for products that are currently installed)}Excel、Word、PowerPoint等时出现错误的产品有效，您应遵循以下建议-

1. 卸载Microsoft Office^{(Microsoft Office)}试用版
2. 修复^(Repair)新的Microsoft Office安装
3. 卸载并重新安装Microsoft Office

要完全解决它，您需要遵循所有步骤。

1]卸载Microsoft Office的试用版^{(1] Uninstall the trial version of Microsoft Office)}

无论^(Whichever)您在Windows计算机上使用的是哪个版本的Microsoft Office ，都可以从“控制面板”中将其卸载。

首先，在任务栏搜索框中搜索^(Taskbar)控制面板^{(Control Panel)}，然后单击相应的结果。之后，单击“程序^{(Programs )}”菜单下的“卸载程序^{(Uninstall a program)}”选项。当View设置为Category时，该选项会出现。

在这里您应该可以找到Microsoft Office^{(Microsoft Office)}的过期副本。您需要选择它并单击卸载^{(Uninstall )}选项。

您可以按照所有屏幕说明完成操作。

2]修复新的Microsoft Office安装^{(2] Repair new Microsoft Office installation)}

如果第一个解决方案没有解决您的问题，您现在需要修复最新的 Microsoft Office 安装。由于Microsoft Office的两个实例之间存在冲突，因此修复应该可以解决问题。

为此，请打开控制面板^{(Control Panel)}并像在第一个解决方案中那样转到卸载程序窗口。^{(Uninstall a program )}之后，从列表中选择Microsoft Office，然后单击更改^{(Change )}按钮。您可能必须在“用户帐户控制^{(User Account Control)}”窗口中选择“是”。^(Yes)

之后，你会得到一个像这样的窗口——

在这里你可以看到两个选项——

1. 快速修复和
2. 在线维修。

快速修复^{(Quick Repair)}方法不需要互联网连接，这应该可以解决您的问题。首先，使用此方法并相应地按照屏幕说明进行操作。如果它没有做任何事情，您必须将您的计算机连接到互联网连接并使用在线修复^{(Online Repair)}选项。它比快速修复^{(Quick Repair)}需要更多时间，并且更有效。

3]卸载并重新安装Microsoft Office^{(3] Uninstall and reinstall Microsoft Office)}

如果使用内置修复工具后问题仍然存在，则该卸载新安装的Microsoft Office并重新安装。这一次，请使用Microsoft 支持和恢复助手^{(Microsoft Support and Recovery Assistant)}，以便您可以完全卸载它。如果你愿意，你可以使用CCleaner来清理残留的垃圾。卸载过程完成后，重新安装并检查问题是否仍然存在。

我希望这些解决方案对您有所帮助。

1] Uninstall the trial version of Microsoft Office

Whichever version of Microsoft Office you were using on your Windows computer, you can uninstall it from Control Panel.

To get started, search for Control Panel in the Taskbar search box and click on the respective result. After that, click the Uninstall a program option under the Programs menu. The option appears when the View is set as Category.

Here you should find the expired copy of Microsoft Office. You need to select it and click the Uninstall option.

You can follow all the screen instructions to get it done.

2] Repair new Microsoft Office installation

3] Uninstall and reinstall Microsoft Office

If the problem remains even after using the in-built repairing tools, it is time to uninstall the new installation of Microsoft Office and reinstall it. This time, do it using Microsoft Support and Recovery Assistant so that you can uninstall it completely. If you wish, you may use CCleaner to clear up the residual junk. Once the uninstallation process is complete, install it again and check if the problem still exists or not.
