MS-DOS

= SUMMARY =

In version 2.0 of Microsoft Works for MS-DOS, the message “Invalid program file” can be caused by a number of problems. This error message indicates that the WORKS.EXE file has been damaged or is defective. This problem may simply require disk replacement or reinstallation; however, it may be a symptom of a virus.

= MORE INFORMATION =

Works will not run if the WORKS.EXE file size has changed. (This is a typical result of a virus attaching itself to an executable file.) If this occurs, the above error message will be displayed. The error message will also be displayed if the WORKS.EXE file has been damaged or corrupted by some other means.

Microsoft uses extensive virus checking procedures throughout the disk manufacturing process. It not possible that a virus was present on the original (unmodified) Works disks when they were shipped from Microsoft.

If you suspect that your computer has a virus and you are using MS-DOS 6.0 or later, run Microsoft Anti-Virus. If you are running an earlier version of MS-DOS, either obtain MS-DOS 6.0 or later, or obtain help from a third- party virus-correction service or vendor.
