Solutions to Fix QuickBooks Error 1327

When it comes to fixing QuickBooks error 1327, you should try the following solutions:

Solution 1: Use the Command Prompt to Remove the Drive Letter

Under this solution, you can remove the drive letter you suspect causing the invalid drive letter error. You use a command that enables you to link and unlink the drive letter to a virtual location, potentially resolving installation issues:

• Launch the Run dialog by pressing Windows + R, input ‘cmd,’ and press Ctrl + Shift + Enter.

• In the Command Prompt, enter the line subst/ P and press Enter, replacing ‘P‘ with your drive letter.
• Exit Command Prompt and attempt to install the QB program.

If replacing the drive letter does not help resolve the error, follow the next troubleshooting step.

Solution 2: Clean Install QuickBooks

If you receive QuickBooks error 1327 while trying to install a previously deleted software, it’s possible you encounter conflicts from the program leftovers. Cleaning the system thoroughly from old or unused software thus becomes critical. Here’s how the Clean Install procedure works for QuickBooks:

Action 1: Prerequisites before Reinstalling QB

• Download the QuickBooks version installer you use.
• Keep your license number ready; it can be found on the original package or in the purchase confirmation email if you bought it online. Alternatively, you can retrieve this information from your account management portal.

Action 2: Remove QuickBooks

• Open the Start menu in Windows and search for “Control Panel” through the search box. Open the Control Panel from the results.
• When the Control Panel opens, find the Uninstall a Program option under the Programs and Features section, directing you to the programs list to locate QuickBooks.
• Locate the version of QuickBooks Desktop you want to remove from the list of programs.
• Tap Uninstall/Change, then select Remove and proceed with Next.
• If you can’t locate this option, sign out and sign back into Windows as an administrator or a user with admin privileges.

Action 3: Rename Installation Folders

• First, display any files you find hidden and can’t access normally.
• Then, access the Windows Start menu and look for ‘File Explorer‘ to open it.
• Locate and launch the folder keeping your QuickBooks company files, typically named the QuickBooks folder. Common directory locations include:
  • C:\ProgramData\Intuit\QuickBooks (year)
  • C:\Users(current user)\AppData\Local\Intuit\QuickBooks (year)
  • C:\Program Files\Intuit\QuickBooks (year)
  • 64-bit QB versions: C:\Program Files (x86)\Intuit\QuickBooks (year)
• Right-click the QB installation folder and choose ‘Rename.’
• Type ‘old‘ to add to the end of the folder name to prevent QuickBooks from accessing it during reinstallation.

If an error message comes up while renaming these installation folders, try this:

• Right-click the Windows Task Bar and tap Task Manager.
• Get into the Processes tab.
• Choose the Name column header for the list sorting.
• Locate the following processes and press End Task on each one: QBDBMgrN.exe, QBDBMgr.exe, QBCFMonitorService.exe, Qbw32.exe.
• Confirm this choice by selecting ‘Yes‘ if prompted with the message, ‘WARNING: Terminating a process can cause undesired results…’

Action 4: Reinstall QuickBooks

Finally, install QuickBooks Desktop again and check if this solution helps resolve the error. If you find the same error reappearing on the system, follow the next troubleshooting solution.

Solution 3: Disconnect the Network Drive

One solution to fix the invalid drive letter error 1327 is disconnecting the network drive you get in File Explorer. The steps involve:

• Press Windows + E and access File Explorer.
• Locate the Network drive.
• Right-click on it and choose Disconnect.

After completing these steps, attempt to reinstall your program. It’s important to note that this solution is effective only when a network drive is visible in File Explorer. If not, refer to the next solution.

Solution 4: Associate the Drive Letter Again with a Temporary Location

This approach enables the linking of a drive letter to a virtual drive location, allowing the installer to identify and use the designated temporary path for the installation of the problematic software.

Note: If the specified temporary path is not present, it is essential to create it before proceeding with the steps outlined below.

• Open the Run dialog with Windows + R keys, then type cmd and press Ctrl + Shift + Enter.
• Enter the script provided below and press Enter, making sure to substitute [Drive Letter] with the actual drive letter: subst [Drive Letter]: C:\temp.
• Close the Command Prompt and proceed to reinstall the software.
• Once again, access the Run dialog through Windows + R, input cmd, and press Ctrl + Shift + Enter.
• Enter the following command and press Enter to disassociate the software from the temporary path: subst /D [Drive Letter].

Follow the next solution if you find the error striking QuickBooks Desktop even after this solution.

Solution 5: Remove and Reconnect a Portable Storage Device

If you’ve detached a portable storage device from your system, reattach it and attempt the QuickBooks installation once again.

Solution 6: Enter as the Built-in Administrator

To enable or disable the built-in Administrator, follow these steps:

• Open the command prompt.
• To activate, enter the command: net user administrator /active:yes.
• Install QuickBooks.
• To deactivate, use the command: net user administrator /active:no.
