Download the full (licensed) version of the software to complete your order. You will need the install password that was sent with your order confirmation to set-up and run the software.

The full version will automatically replace the trial version or any previous version without losing any diagrams you have saved.

If you have a valid install password from a previous purchase, you can use this download to upgrade to the current version or replace a lost or corrupted installation using your previous password. However, install passwords may expire and you may need to contact us to request re-authorization (see below).

* If you encounter an error or warning when trying to download the file, it is likely due to a feature of Windows Defender called SmartScreen that is commonly enabled by default in Windows 11 with the Microsoft Edge browser. To disable this feature in the Microsoft Edge browser, click on the three dots and choose "Settings", then select "Privacy Search and Services", scroll down to the "Security" section and turn off the SmartScreen option. Then try again to download the file. You may want to re-enable SmartScreen after the download is complete.

It is normal to encounter warnings when downloading a file to your computer or when running a setup file. We take reasonable precautions so that the install files we provide on pacestar.com are virus-free and safe to use on your computer. Windows and popular malware and virus detection software may not "recognize" our files. We test our installers for viruses and malware every time we upload a file, as we have for many years. Plus, other web sites test our files independently and certify them as safe.
