It is essential that you verify the integrity of the downloaded installer file to ensure that the file you downloaded is not corrupt. For this verification, Fiorano provides pre-calculated hash values using SHA1 and MD5 Algorithms for each installer.


This exercise needs to be carried out right after downloading the Installer and before you get into the installation procedure or before you open the Installation Wizard.

Checking the Integrity

You may use the 'Fiorano Checksum Utility' or other command line programs like md5sum/sha1sum/md5/sha1 to check the integrity, both of which are explained below.

Fiorano Checksum Utility

Checksum is a digit representing the sum of the correct digits in a piece of stored or transmitted digital data, against which later comparisons can be made to detect errors in the data. Fiorano Checksum Utility, which utilizes this principle to check integrity of the downloaded file, is the simple way between the two.

Perform the following steps to use the utility:

  1. Download the Fiorano checksum utility.
  2. Open the text file present in the checksum zip file and answer the short questionnaire present in the file.
  3. Execute ant command.

By this, the command prompt displays the Integrity Check result for the downloaded installer file.


The Fiorano checksum utility uses Java 1.6 or higher versions and ANT 1.7.0 or higher.

Using Command line Programs

To check the integrity using command line programs, open the console and perform the following actions:

  1. Run any one of the following commands:
    1. md5sum/sha1sum
    2. md5/sha1
    For example, if you want to check the file fsoa_***.exe using MD5, type the command below in the terminal:
    $ md5sum fsoa_***.exe
  2. After running this command, md5sum prints out the 128-bit hash value. Compare this resulting string with the hash value provided at the product downloads link.
  3. If both values are identical, then the download is accurate; else it is corrupt.

Similarly, you can perform the above steps after executing the following command using 'sha1sum' to print out 160-bit hash value for fsoa_***.tar.gz file:

$ sha1sum fsoa_***.tar.gz


Corrupt Installer file

In case you find that the downloaded Installer file is corrupt, please download the installer again and repeat the steps as above.
