The ZipStream Registration utility is used to register your copy of ZipStream. The two numbers you need are supplied with the packaged product. Click on Cancel if you are not registering at this time.
If you do not run the registration utility ZipStream's automatic compression system will cease to operate after 45 days. However, the interactive compression and decompression programs (ZSPack and ZSUnpack) will always continue to operate.

When the utility is run it will display a window for the entry of the two part registration number, as shown above. You should enter the two numbers supplied with the product and then click on the OK button.
The registration process will take several seconds, and when complete, it will display a message indicating the success of the operation. If the operation is successful, the registration process is complete. If unsuccessful this means that you have typed in one of the two numbers incorrectly, and you should retype them and try again.
