In this case, proceed as follows:

  1. Delete all installed Java versions from the system (for this, go to Start - Control Panel - Programs and Features).
  2. Run offline version of the AxxonSoft Platform Calculator (see Downloading and starting offline version).
  3. Install the proposed Java version.
