The updates on
this page will not update v. 3.0 or 4.0.
These maintenance updates will bring your EZNEC or EZNEC+ v. 5.0 program up to the latest revision by installing improvements, bug fixes, and corrections to the on-line manual.
The EZNEC and EZNEC+ v. 5.0 maintenance updates won't update the demo or pro versions, and will be of no use if you haven't installed the appropriate version of EZNEC v. 5.0. The version of the demo available on the web is generally the same as the latest maintenance update, so you can update a demo version if desired by downloading and installing the current demo.

number on the top line (for example, 5.0.6).
2. Check the current update revision number below. If it's the same as your program revision, there's no need to download the update. Note: Revision numbers are separate integers, not decimal fractions. So, for example, version 5.0.14 (revision 14) is later than version 5.0.2 (revision 2).
3. If your EZNEC or EZNEC+ v. 5.0 revision is earlier than the current update revision, click one of the links below to start the download. First, note that some updates may apply only to EZNEC, some to EZNEC+, and some to both. Be sure you download one which is appropriate for your program type. Next, note that various updates may only update certain revision numbers. If more than one update applies to your program, you can choose any that does -- the only difference will be in the size of the file to download, and the end result will be the same.
4. After downloading the file and before starting the update, turn off Norton or other virus or anti-spyware protection if you have it running in the background. It can cause the installation to hang or other processes to fail. You can restore normal anti-virus and -spyware protection after the installation is finished.
5. Run the file by double-clicking it in Windows Explorer, or by clicking the Windows Start button at the lower left of your screen, selecting Run, entering the path and file name, and clicking Ok. You'll see the installation proceed.
6. Save the update file for later use in case you need to update EZNEC or EZNEC+ v. 5.0 after re-installing it or installing it on another computer.
