Error 1327. Invalid Drive x


x is a drive letter.


This error comes from InstallShield, the install wrapper that we use to package our software.

InstallShield verifies all Standard Windows folders are available before installing. The drive specified in the message and/or one of the standard Windows Folders on was not writeable during the install. Your drive letters may have changed and one of the Standard Windows Folders points to a drive letter than no longer exists.


Temporary Solution

A temporary solution is to reassign the problem drive to a folder that exists.

1.Open a Windows command prompt as administrator. (Start, All Programs, Accessories, right click on Command Prompt and select run as administrator from the context menu.)
2.Type the follows command in the command prompt window and press enter:
subst x: c:\
where x is the drive letter specified in the error message.
3.Retry the install.

The reassignment will disappear after the computer is rebooted.

Permanent Solution

The permanent solution is to add the missing drive back to your configuration or to correct the standard windows folder registry entry that points to the missing drive and point it to a drive that exists. 

The following steps show how to verify and correct the standard window folder entries. This involves modifying the registry. Modifying the registry incorrectly can damage your Windows system. Make sure you back up the registry before you make any changes.

1. Run regedit.
2.Locate the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
3.In the right pane, look for any values that contain the drive letter specified in the error message. Right click on the value and select  Modify from the context menu.
4.Change the erroneous drive letter to a valid drive letter. For example if the value is "X:\Users\Administrator\AppData\Roaming", change it to "C:\Users\Administrator\AppData\Roaming" or whatever location is appropriate for your configuration.
5.Repeat steps 3 and 4 for every incorrect value.
6.Repeat steps 3 through 5 for the following registry keys:
KEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
7.Retry the install.
