In E-Prime 22.214.171.124 there is a known issue when attempting to open E-Prime 2.0 while both E-Prime 2.0 and E-Prime 3.0 License Keys are attached. This occurs when E-Prime 2.0 searches for a License Key and finds the E-Prime 3.0 License Key first and determines it is not allowable. This only occurs when the "Key ID" property listed in http://localhost:1947/ is lower for E-Prime 3.0 than it is for E-Prime 2.0.
This issue has been resolved in E-Prime 126.96.36.199.
Users with an E-Prime 3.0 Upgrade License that was shipped with E-Prime 188.8.131.52 will also need to contact support to electronically update their License Key.
This only applies to users who need to open E-Prime 2.0 while both E-Prime 2.0 and E-Prime 3.0 License Keys are attached. A workaround is to detach the E-Prime 3.0 License Key while using E-Prime 2.0.
Please note: There are no other differences (e.g., Runtime) between 184.108.40.206 and 220.127.116.11. Users do not need to have any concerns about updating.
