    3.Environment variable debug, not ok.

    4.Uninstall recently installed tools, not ok.

    5.Repair OS, not ok.

     

    On windows10 22H2, default have ' Microsoft Visual C++ 2015-2022'.

    'FCCryptDLL.dll' missing(not x86 folder one). Seek another computer, install same FortiClient, copy 'FCCryptDLL.dll', solved.

    We encountered the same issue but didn’t need to remove anything. We simply had to repair Microsoft Visual C++ 2015-2022. After the repair, FortiClient started working again.
     
    Microsoft Visual C++ 2015-2022 has been the cause of many issues this week, affecting applications like Teams and others.
