Paste IDE compiler output.
Does it say you have multiple libraries for the same thing?
OK finally got things working! V0.4.4 installed

The initial problem stemmed from http://www.blynk.io/demo/ maybe update the document
SETTING UP ARDUINO IDE
Install latest Arduino IDE.
Download latest Blynk release package: Blynk_Release_v0.3.10.zip. It contains 5 libraries, please copy them to Arduino Libraries folder. If you don’t know how to do this, please follow manual installation guide.
@Badge could you please indicate why you were struggling to install 0.4.4 as it may help others.
Edit: see you have posted the problem.
@Dmitriy could you perhaps ensure that all your documentation links to the real latest release folder rather than a specific release that will be out of date in a week or two.
I know it is useful to direct users to a specific zip file for them to click on but with Blynk being so progressive it causes more problems than it solves. The links should just be to the latest releases folder at https://github.com/blynkkk/blynk-library/releases
This way some new users might actually read the release notes and understand how the libraries are to be structured. If you provide a zip link they never see the release notes.
I suggest the same for other Blynkers posting to hackster, instructables etc, don’t provide zip links and warn users that any sketch you include might need revisions to work with the latest libraries.
@Pavel presumably your “Plant pot demo” sketches for iOS and Android are on GitHub and being updated to reflect any Blynk library changes.
