If you see 2.5 in the about box, this means you do not have a clean install of v2.6

So, please first fully uninstall TMS WEB Core via Windows Control Panel Add/Remove software. After uninstall, verify in your Delphi IDE there is no more trace of TMS WEB Core.

When Delphi is clean, do an install of v2.6
