Is WebCore 3.0 supposed to be installable on Lazarus?

Hi TMS, I am experiencing problems installing on Lazarus 4.8. There are a lot of VLC.* and other unknown units referenced in the code.

Maybe missing some IFDEF's? Or maybe some new installation process?

Sorry, we not longer actively support latest Lazarus versions for TMS WEB Core latest version.
There have been constant breaking changes done in Lazarus that requires constant work for too few customers, so unfortunately, this isn't a financially feasible situation anymore.

Damn, that's 195€ down the toilet then.

You should still be able to install it in an older Lazarus version, in the free Delphi Community Edition or any other Delphi version newer than v10
