  1. Unable to register DLLs and OCXs in Windows Enterprise 1909 build


    Hi all,


    I have installed Windows 10 Enterprise version with latest 1909 build, from then the DLLs and OCXs of my application are not registering. I'm facing the issue"The module xxxx.dll may not be compatible with the version of Windows that you are running.Check if the module is compatible with an x86 32-bit or x64 64-bit version of regsvr32.exe". My DLLs and OCXs are of 32-bit.


    I tried registering from command prompt with elevated permissions in the following ways but all of them prompted me the same issue.


    regsvr32 xxxx.dll

    %systemroot%\SysWoW64\regsvr32.exe xxxx.dll

    %systemroot%\System32\regsvr32.exe xxxx.dll


    Please let me know if there is any solution to resolve the issue. Thanks in advance.

    :)

    Legacy OCX fails to register on Windows 10 Pro

    I have a need to register an OCX for a legacy application on Windows 10 Pro. The OCX registers without issue on a Windows 10 Enterprise machine, but does not register on W10 Pro. No error message at all -- just the blue spinning circle for 20 seconds or
    so and then nothing.

    It is a 32bit application, so we have tried without success regsvr32 from both system32 and syswow64 and using "Run as administrator". Regsvr32 shows as still running in task manager after each attempt to register.

    We have tried disabling virus protection, but still no success.

    Restarting in safe mode, we are able to successfully register the ocx using syswow64\regsvr32 and the app runs as expected in safe mode with networking. Restart to full OS and the app hangs up when attempting to call the functions in the OCX.

    W10 enterprise has no issue registering the OCX or running the app.

    Any suggestions appreciated.
