Integrated Development Environment for the 8-bit Microchip AVR, AVR8X, AVR DA, AVR DB, AVR DD, AVR EA and XMEGA Microcontrollers
CodeVisionAVR is designed to be used both in its own IDE and also as an Extension in Microchip Studio 7.
It is compatible with Windows® Vista, 7, 8, 10 and 11, 32 and 64-bit operating systems.
For the Extension to be installed correctly, Microchip Studio 7 must be already present on the computer, before the CodeVisionAVR installer is launched.

Using the CodeVisionAVR Extension for Microchip Studio
CodeVisionAVR C Compiler Reference|Using the AVR Studio 4.19 Debugger
and in the chapters: 1 and 4.21 of the CodeVisionAVR User Manual.
Due to high software piracy we were forced to protect our product with the advanced code compression and encryption techniques implemented by the commercial product WinLicense from Oreans Technologies.
However these techniques may trigger false alarms in some antivirurses like BitDefender, ESET, AVAST or AVG, preventing CodeVisionAVR from being executed.
In such cases you need to add the whole CodeVisionAVR installation \BIN folder to the antivirus file
exclusion list.
When installing and using Atmel Studio and CodeVisionAVR, the user must be logged in as Administrator in Windows.
When installing CodeVisionAVR under Windows 8 and 8.1, please right click on the CodeVisionAVR, LCD Vision and Atmel Studio icons on the desktop, select Properties|Advanced and enable the Run as Administrator option
During Atmel Studio installation under Windows XP, the checkbox Protect my computer and data from unauthorized program activity must be unchecked.
If the older Atmel Studio 6 is present on the computer, it must be first fully uninstalled before installing Microchip Studio 7 and CodeVisionAVR.
After uninstalling the old Atmel Studio, the remaining C:\Program Files (x86)\Atmel\Atmel Studio 6.x directory and files must be deleted.
The Naggy extension for Atmel Studio is not compatible with CodeVisionAVR.
When using CodeVisionAVR, Naggy must be disabled from the Microchip Studio's menu: Tools|Disable Naggy.
After Microchip Studio 7 has been installed, you may unzip the downloaded file in a temporary directory and launch the CodeVisionAVR installer.
Note: When installing CodeVisionAVR under Windows Vista, the User Account Control must be disabled, as outlined in the instructions.

CodeVisionAVR can be also used with its own IDE without having to install Microchip Studio.
This may be useful if the user wants to preserve disk space or has a slower computer.

Some users may wish to install both Microchip Studio 7 and the old AVR Studio 4.19 on the same computer.
In this case the debugger to be used can be selected in the Settings|Debugger menu of the CodeVisionAVR IDE.

Details about using CodeVisionAVR with these debuggers are available in the Help topics:
Free, 4kbytes code size limited version. Includes also the
