Why is an Error Received While Downloading to the Target PC, But the
Host PC Indicates a Successful Download?
If you boot up a target PC with a boot disk from a previous release, then build
and download a target application from a host PC running a later release of the
xPC Target software, the host PC might indicate a successful download.
However, the target PC might display an error message like the following:

This is because the xPC Target software on the boot disk did not match the
version of xPC Target software running on the host PC. As a general rule, you

To resolve this, create a new boot disk using the host PC xPC Target software
and reboot the target PC with the new boot disk.
Note You should properly label and store old boot disks in case you need to
use them again.
