    Hello, We met a problem with x64 verison on framework 4.5.2. Take a look at screenshot in attachment. If I switch project to x86 version and use x86 version of ocx - everything works. Could you please give me some solution or maybe simple example project vs2015 which works on x64?

    I have tried a lot variants, but always when c1query added as control and have linked c1queryframe, application crashes with "Attempted to read or write protected memory". Ocx file info in the second attachment.

    Hi Pragati

    This case is very important for us, because we cannot release new version of our app with broken query control.
    Could you please keep this problem and solution public, so management team can track progress

    Thank you

    Hi,

    I understand that. This case is with the developers on high priority. Will update the thread once there is anything from them.

    Note: Our ActiveX controls are in maintenance mode.

    Thanks,

    Hi,

    There have been no response from the Development Team yet.
    Hence I have asked for an ETA on this case and have once again raised concern on this issue.
    Also, the issue is currently marked with top-most priority in the To-Do list.

    I would update you as soon as we receive any updates from them.

    Hi,

    We have tried verifying the behavior on a Windows 7 64 bit machine at our end. The 64 bit version runs correctly on a Windows 7 machine. However, to make the 64 bit to work on Win7, it was necessary to configure explicit 32 bit (x86) and 64 bit (x64) builds in the sample. AnyCPU is inappropriate for all our controls because they are native code and not .NET. If the program process starts as 32 bit and an attempt to load a 64 bit OCX is made, the program will crash. Similarly, the opposite is also true.

    But on a Windows 10 machine, there seems to be some problems. The developers are looking into it but there is no ETA as of now. It will take time in fixing.

    Note: Our ActiveX controls are in maintenance mode.

    Thanks,

    Hi Pragati

    This problem is still very important for our clients, because we need to allow them work with x64 application
    What is ETA for resolution of this problem?

    Thank you
