A quick search will reveal the answer: https://www.b4x.com/android/forum/pages/results/?query=Unsupported+major.minor+version+52.0

You need to install Java 8.

 

[LéonE]

error on compile
Installing file to device. Error
The system cannot find the file specified
also
clicking (where ever) in/on the sdk manager the window closes

 

[Erel]

Are you using B4A Sdk Manager and downloaded all recommended items?

Can you post a screenshot of Tools - Paths Configuration dialog?

You can transfer the license to the new computer.
