Listed below are some free tools that Chilli Source provide to assist their customers. You can download and use these tools as suits your needs.

crc32.exe

This software is used to check the integrity of installer archives downloaded from the Chilli Source web pages. CRC32 is freeware.

The CRC program calculates a "cyclical redundancy check" value for the files you specify. In effect, it performs a complex calculation on every byte in the file, generating a unique number for the file in question. If so much as a single byte in the file being checked were to change, the cyclical redundancy check value for that file would also change.

If you know the CRC value for a file, you can compare it with the CRC value generated by this software after the file has been downloaded to ascertain whether the file was damaged in transit. The odds of two files having the same CRC value are along the lines of one in 4,294,967,296.

The CRC values for selected downloadable files at the Chilli Source web pages are listed on the file download page.

Here's what a CRC check looks like. Please note that this example illustrates the check for a specific build of Database Design Studio - Lite. If you use this software to check a later version of DDS-Lite, the CRC check value will change do not compare your software to this example.

To use the CRC32 tool:

1.

Download the file crc32.exe into the same folder as the Chilli Source software installer file for the application.

2.

Open a command prompt window and change into the same folder as the crc32 tool and software installer file.

3.

Enter the command: crc32 filename.exe
Where filename.exe is the full name of the software installer file. The software will do a calculation and then display an eight-character CRC integrity check. Compare this to the one published at our download link. If they match, the files are identical - nothing got damaged in transit - and it's safe to run the installer and use your downloaded software.

It's important to keep in mind that very few downloads get damaged over the internet - the CRC integrity check system offers you additional insurance that nothing nasty is about to happen, and is exceedingly useful in working through installation problems. It will quickly ascertain whether you have a damaged download.
