What is Sage 50 Error 1327 Invalid Drive?

Error 1327. Invalid Drive: Drive Letter

The Windows Installer attempts to read data from a drive that is either not present or absent in the system. The drive letter indicated in the error message immediately points us to the point of failure in our troubleshooting process.

The system error arises because the registry is unable to find the physical drives listed in its software records. Sage 50 generates the error when it attempts to locate a non-existent location that the system registry indicates.

The error appears in different situations during standard program operation:

1. Installation: When installing Sage 50 its setup process tries to use temporary space on a hard drive that has been removed.
2. Updates: The Sage 50 update procedure may try to access the previously used drive for configuration file and data locations.
3. Opening the Application: When you start Sage 50 the program attempts to retrieve configuration details from an outdated hard drive.
4. Uninstalling: The system cannot detect the drive entry stored in the registry while you try to uninstall.

The consequences of this error depend on how much Sage 50 is a necessary part of your financial operations but they can both disrupt work flow and stop business processes.
