When you are installing FoxPro for Windows, the following error message occurs:

File copy operation failed - incorrect number of bytes written


This error message may occur when a virus-protection utility is installed on the system.


The virus-protection utility must be turned off or removed from the system until FoxPro for Windows has been installed.


This behavior is by design.
