如果当您尝试在 Windows 10 设备上安装或卸载任何程序时，收到指示错误 1327 – 无效驱动器(Error 1327 – Invalid Drive)的提示，那么这篇文章旨在帮助您。大多数用户在安装 Microsoft Office 期间都会遇到此错误(error during Microsoft Office installation)。在这篇文章中，我们将找出潜在的原因，并提供您可以尝试有效解决问题的最合适的解决方案。
出现此错误的原因如下：
- 当用于安装程序的驱动器无效时。
- 安装程序正在尝试在未映射的网络位置上完成操作。
错误 1327 – 无效的驱动器
如果您遇到此问题，您可以尝试以下我们推荐的解决方案（不分先后顺序），看看是否有助于解决问题。
- 运行(Run)第三方软件卸载程序
- 有问题的驱动器的替代(Substitute)路径
- 修改注册表
- 断开网络驱动器
- 映射未映射的网络驱动器
- 登录另一个用户帐户
让我们看一下关于列出的每个解决方案所涉及的过程的描述。
1]运行(Run)第三方软件卸载程序
如果在您尝试安装以前删除的软件时发生这种情况，则旧程序的一些剩余/残留文件可能会产生冲突。在这种情况下，您应该使用第三方软件卸载(use a third-party software uninstaller)程序从旧的或未使用的软件中彻底清除系统。
2]有问题的驱动器的替代(Substitute)路径
此解决方案要求您使用SUBST命令替换有问题的驱动器的路径并重定向到正确的驱动器。就是这样：
subst X: Y:\
- 命令成功执行后，关闭提升的CMD提示符并重新启动计算机。
在启动时，重复之前导致问题的任务，看看问题现在是否已解决。如果没有，请尝试下一个解决方案。
3]修改注册表
由于这是注册表操作，建议您备份注册表(back up the registry) 或 创建系统还原点 作为必要的预防措施。完成后，您可以执行以下操作：
- 按Windows key + R调用“运行”对话框。
- 在“运行”对话框中，键入
regedit并按 Enter 以打开注册表编辑器(open Registry Editor)。 - 导航或跳转到下面的注册表项路径：
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
- 在右侧窗格中，确定错误提示中显示有问题的驱动器号的任何条目（在本例中
K为 ），并将其更改为操作系统驱动器（通常为C）。 - 完成后，单击确定(OK)以保存更改。
- 重启你的电脑。这个问题应该得到解决。
现在，如果您在安装较旧的Microsoft Office时遇到问题，或者在尝试将当前的Office安装更新到较新版本时，该问题也可能是由无效的LocalCacheDrive注册表项引起的。在这种情况下，您可以通过将LocalCacheDrive修改为有效字母来解决此问题。就是这样：
采取必要的预防措施，然后进行如下操作：
- 在注册表编辑器(Registry Editor)中，导航或跳转到下面的注册表项路径：
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\
- 在该位置的左窗格中，单击与您的Office安装关联的子文件夹。请参阅下表将前两位数字与相应的Office套件版本进行比较。
| First two digits | Office version |
|---|
| 11 | Microsoft Office 2003 |
| 12 | Microsoft Office 2007 |
| 14 | Microsoft Office 2010 |
| 15 | Microsoft Office 2013 |
| 16 | Microsoft Office 2016/19 |
- 选择交付(Delivery) 密钥。
- 在右窗格中，双击LocalCacheDrive 条目以编辑其属性。
- 在属性窗口中，将 值数据(Value Data)设置 为您的 操作系统驱动器(OS drive) （最常见 的是C）。
- 单击确定( OK) 以保存更改。
- 重启你的电脑。
现在应该解决这个问题。否则，请尝试下一个解决方案。
4]断开网络驱动器
仅当网络驱动器出现在文件资源管理(File Explorer)器中的此 PC 中时，断开网络驱动器解决方案才有效。
要断开网络驱动器，请执行以下操作：
- 按Windows key + E打开文件资源管理器(open File Explorer)。
- 单击这台电脑(This PC)。
- 按CTRL + F1键打开带有工具的功能区。
- 单击映射网络驱动器(Map network drive)。
- 从下拉列表中选择断开网络驱动器。(Disconnect network drive)
重复之前触发错误的操作并查看问题是否已解决。如果没有，请尝试下一个解决方案。
5]映射未映射的网络驱动器
如果错误提示中指示的驱动器实际上未映射，则很可能您没有在网络驱动器上安装应用程序的权限。在这种情况下，您可以映射网络驱动器(map the network drive)，看看是否有帮助。
5]登录另一个用户帐户
您也可以尝试登录另一个用户帐户，然后尝试安装或卸载应用程序/程序，看看错误是否仍然存在。如果您的机器上没有辅助用户帐户，则需要创建一个新帐户。
希望这可以帮助！
Error 1327 Invalid Drive when installing or uninstalling programs
If when you аttempt to instаll or uninstall any program on your Windows 10 device, you receive the prompt indicating Error 1327 – Invalid Drive, then this post is intended to help you. Most users will encounter this error during Microsoft Office installation. In this post, we will identify the potential causes, as well as provide the most suitable solutions you can try to effectively resolve the issue.
This error occurs due to the following reasons:
- When the drive being used for the installation of the program is not valid.
- The installer is trying to complete the operation on a network location that is not mapped.
Error 1327 – Invalid Drive
If you’re faced with this issue, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue.
- Run third-party software uninstaller
- Substitute path of the problematic drive
- Modify the registry
- Disconnect network drive
- Map the unmapped network drive
- Sign into another user account
Let’s take a look at the description of the process involved concerning each of the listed solutions.
1] Run third-party software uninstaller
If this occurs when you are trying to install software that was previously removed, it’s likely some of the leftover/residual files of the old program might create a conflict. In this case, you should use a third-party software uninstaller to completely clean the system from old or unused software.
2] Substitute path of the problematic drive
This solution requires you to the SUBST command to substitute the path of the problematic drive and redirect to a correct drive. Here’s how:
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type
cmd and then press CTRL + SHIFT + ENTER to open Command Prompt in admin/elevated mode. - In the command prompt window, type the command below and hit Enter – where
X is the placeholder for the non-existent drive (the drive letter shown on the error prompt) and Y is the placeholder for your OS drive (where Windows 10 is installed; usually C).
subst X: Y:\
- Once the command executes successfully, close the elevated CMD prompt and restart your computer.
On boot, repeat the task that was previously causing the problem and see if the problem is now resolved. If not, try the next solution.
3] Modify the registry
Since this is a registry operation, it is recommended that you back up the registry or create a system restore point as necessary precautionary measures. Once done, you can proceed as follows:
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type
regedit and hit Enter to open Registry Editor. - Navigate or jump to the registry key path below:
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
- On the right pane, identify any entry that has the problematic drive letter shown on the error prompt (in this case
K) and change it to the OS drive (usually C). - Once done, click OK to save changes.
- Restart your computer. The issue should be resolved.
Now, if you’re encountering the problem with an older Microsoft Office installation or when trying to update your current Office installation to a newer version, the issue can also be caused by LocalCacheDrive registry entry that is invalid. In this case, you can fix the issue by modifying the LocalCacheDrive to a valid letter. Here’s how:
Take the necessary precautionary measure, then proceed as follows:
- In Registry Editor, navigate or jump to the registry key path below:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\
- At the location, on the left pane, click the subfolder associated with your Office installation. See table below to compare the first two digits with the corresponding Office suite version.
| First two digits | Office version |
|---|
| 11 | Microsoft Office 2003 |
| 12 | Microsoft Office 2007 |
| 14 | Microsoft Office 2010 |
| 15 | Microsoft Office 2013 |
| 16 | Microsoft Office 2016/19 |
- Select the Delivery key.
- On the right pane, double-click on LocalCacheDrive entry to edit its properties.
- In the properties window, set the Value Data to your OS drive (most commonly C).
- Click OK to save the changes.
- Restart your computer.
The issue should be resolved now. Otherwise, try the next solution.
4] Disconnect network drive
Disconnecting the network drive solution will work only if the network drive appears in This PC in File Explorer.
To disconnect the network drive, do the following:
- Press Windows key + E to open File Explorer.
- Click This PC.
- Press CTRL + F1 key to open ribbon with tools.
- Click Map network drive.
- Select Disconnect network drive from the drop-down.
Repeat the action that previously triggered the error and see if the issue has been resolved. If not, try the next solution.
5] Map the unmapped network drive
If the drive that’s indicated on the error prompt is not actually mapped, it’s very likely that you don’t have permission to install the application on the network drive. In this case, you can map the network drive and see if that helps.
5] Sign into another user account
You can also try to sign in to another user account, then try the install or uninstall of the app/program and see if the error still occurs. If you don’t have a secondary user account on your machine, you need to create a new account.
Hope this helps!
