Installation Error - NoClassDefFoundError

I want to install VP 12.2 on my MBP, but it was stopped by some error. The error is that 『could not initialize class com.install4j.runtime.installer.helper.InstallUtil』. I hava tried to change my JRE version, but it doesn’t work.

Hi Holen,

The VP 12.2 actually is no longer supported. Would you please send your license key to so that we can lookup your license record and see did your license entitle for upgrade to newer version? Look forward to hearing from you.

Best regards,
