Engineering Economic Analysis పాత వెర్షన్లు డౌన్‌లోడ్

Engineering Economic Analysis v3.1 contains the following changes:
- Implemented a new project management system. Each project is stored in a single file that can be placed anywhere and moved or renamed at any time. The program remembers the location of project files and displays them on a ‘most recently used projects’ list.
- Implemented a new software security scheme using a license key. The license key is issued when you first license the software and expires when the license expires. A new key is provided each time you renew the license to extend operation for another year. Note that the license key is associated with your license, not a particular version of the software.
- Implemented a new installation approach. Version 3.1 installs as a standalone software program.
Installation of Carrier X Builder Framework is no longer required.
