IDL 7.1 Release Notes

There are two installation packages:
idl711win32_setup.exe for 32-bit Windows systems
idl711win64_setup.exe for 64-bit Windows systems



Note If you have a 64-bit Windows system, use the 64-bit installation package. It includes both 32-bit and 64-bit versions of IDL.



The installation program will un-compress files to a temporary space on your system drive. There must be sufficient space (500 MB) on your system drive before the installation process can begin. After installation, IDL 7.1 requires approximately 380 MB of disk space.
Windows XP and Vista are supported. (On 32-bit Windows XP systems, XP Service Pack 2 is required.)
You need Administrator privileges to install IDL. If you do not have such privileges, the installation process will fail because it cannot modify the system configuration.

"I don't understand the grammar." Solution: Remember, Peppa uses basic sentence endings like -어요/아요 (polite informal) and -이다 (to be). Don't worry about complex -습니다 forms yet. Focus on nouns and verbs.

Before diving into the "how," let's look at the "why." Peppa Pig is designed for preschoolers, which means the language complexity is perfect for A2-B1 level Korean learners.

You get the charm of a beloved character, the clarity of preschool dialogue, and the safety net of English text.

You’ll hear common verbs and greetings over and over.

It’s cute. It’s effective. And it’s free from the pressure of a classroom.

Adult learners benefit specifically because:

content in Korean with English subtitles is a popular way to practice the language because the show uses simple, everyday vocabulary and short sentences. In Korea, the show is titled 꿀꿀! 페파는 즐거워 Ggul-ggul! Peppa-neun Jeul-geo-wo Where to Watch

If you have a Korean friend or a Korean Apple ID, platforms like or Wavve host hundreds of Peppa Pig episodes in Korean. The bad news: They rarely offer English subtitles.

IDL 7.1 requires approximately 400 MB of disk space.
Mac OS 10.5.1 (or later) is supported.
The Apple X11 Window System must be installed from the Mac OS X CD-ROM (it is not installed by default).
If you plan to install IDL in a default directory (/Applications/), be sure you have administrator privileges before running the installer.
