Description

Due to a problem in the Quartus^® Prime Pro Edition Installer for software version 25.3, it installs an older version of Ashling* RiscFree* IDE for Altera^® software. 

For example: 

• Quartus^® Prime Pro Edition software version 25.1 is paired with Ashling* RiscFree* IDE for Altera^® v25.1.1 (dated as 31^st Jan 2025). 

• Quartus^® Prime Pro Edition software version 25.1.1 is paired with Ashling* RiscFree* IDE for Altera^® v25.2.1 (dated as 9^th May 2025). 

• However, Quartus^® Prime Pro Edition software version 25.3 is paired with Ashling* RiscFree* IDE for Altera^® v25.1.1 (dated as 31^st Jan 2025). Thus, an older Ashling* RiscFree* IDE for Altera software is installed.
