ID: Q120246

The information in this article applies to:

Microsoft FoxPro for MS-DOS, versions 2.0, 2.5x, 2.6
Microsoft FoxPro for Windows, versions 2.5x, 2.6x

SYMPTOMS

When an .EXE file that was created with the FoxPro Distribution Kit is executed, one of the following error messages is displayed:

Cannot read from drive <drive name>

-or-

Error reading drive <drive name>

This problem occurs when the .EXE file is executed on a machine other than the machine on which it was created.

NOTE: In addition to the above error, when the same problem occurs on Windows NT, an "I/O operation failed" error message is returned.

CAUSE

The .EXE file was created on a computer with drive letters higher than C.

Physical and logical drive types that can cause this problem include the following:

RAM drives

Compressed drives (such as DoubleSpace, DriveSpace, Stacker)

Removable drives (such as Bernoulli)

CD-ROM drives

Hard disk drives with more than one partition

Network drives

This problem can also occur on systems with more than one physical hard disk drive.

RESOLUTION

Create the .EXE file on a computer that does not have a drive letter higher than C. The computer on which the .EXE file is created should not have any physical or logical drives other than drive C.

NOTE: There are several potential causes for this problem. Some of these causes are documented in other Knowledge Base articles. If the resolution documented in this article does not resolve the problem, please see the following articles in the Microsoft Knowledge Base:
