Gary,
Went to the internet and asked what a CRC error was. This is the answer I got at a Q&A site..
Q: I receive a CRC error when I try to install the software, what does this mean?
A CRC error usually means that the installation file was not completely downloaded, or it was corrupted during the transfer. CRC (Cyclic redundancy checking) is a technique used to verify that a block of data transferred over the network was not corrupted in transit, for more information see

I've taken the liberty of reporting this to MTU in your behalf.
