Captivate Classic 11.8.2.254 files install to C:\ProgramFiles\Adobe\ folder on Windows 10. Should install to "Adobe Captivate 2019 x64" subfolder. I installed 11.8.2.254 via the Captivate installer after running "Check for Updates" from the Help menu of the previous version. Installation was successful and 11.8.2.254 runs without any apparent issues. Performed the same update on another Win 10 laptop and it too had Captivate files installed to the C:\ProgramFiles\Adobe\ folder.
