After downloading the software package from Salesforce, use a checksum calculator (freely available from many third-party vendors) to ensure that the number of bits transmitted is same as the number of bits in your downloaded file. The example used here is available from Sigma Informatics, but Sonus does not specifically endorse or recommend any particular third-party application.
To calculate the checksum, perform the following steps:
Locate and download a free checksum calculator.
