See the following document for typical "Windows System Error Codes (exit codes) Description", find code 1625 in the listing: 

1625 = This installation is forbidden by system policy. Contact your system administrator.

Therefore it seems that this issue is a problem with the system / company policy. Could be that installation is blocked from a CD by administrator.
