Error 1327: Invalid Drive
This error has several causes. One cause is that the installation was created with a hard-coded path to a drive letter that does not exist on the machine. If this is the case then there is no way to make the installation install to a different drive letter. The software vendor must be contacted. Other causes include:
i. The CD-ROM or DVD-ROM drive letter has changed since a previous install.
ii. You have changed the drive letter of the hard disk that the operating system is installed on, for example, drive C.
iii. This behavior may occur if a registry key contains an incorrect value in a Data field.
