Actually, there is a difference. The Community Edition (trial version) downloaded from http://hp.com/go/loadrunner is smaller than the one downloaded from the website after a license is purchased. The Community Edition has a smaller Standalone Applications folder because it doesn't have installers used by Performance Center users. And it does not have localization resources. LoadRunner 12.0 is available in 11 language: English, Simplified Chinese, Japanese, Korean, Russian, French, Dutch, German, Italian, Spanish, and Brazilian Portuguese. take a look at my 2:42 minute video at https://www.youtube.com/watch?v=TWAe4fMo6U0&index=2&list=PLsnl23XQgokFlq2T0tKfKyC9ucd7Jyvv5.
