    Where can I find all COM objects created with Powershell?

    I am currently migrating any type of PHP website from one server running Windows Server 2003 and PHP 5.2 to a server running Windows Server and r2 PHP 5.6.35 this year. One scenario is that when I create a meaningful COM object, I get a big “Class not registered” error:

    How do I fix a class that is not registered?

    Turn off iCloud.Save ExplorerFrame again.Check your tough motivation.Use component services.Use a great browser.Create a new Microsoft script.Install Microsoft Edge on your kaas a browser interaction.Make sure the Internet Explorer ETW Collector Service is running.

      $ obj = new COM ('DllName.ClassName') may die ("Unable to create COM object"); 

    • COM DLL is registered on this server (either by checking the computer’s registry or using PowerShell).
    • PHP installation is done in 32 bits (PHP_INT_SIZE is 4).

    I really think the next thing I can look at is the More dialog box.Additional Settings ”, which was mentioned in the answer to the first question above, but where can I find it? The server actually used is Apache installed as part of WAMP, but I think the problem is at a lower level.

    Looks like the solution was to use a registry hack known outside of the first linked question in the blog post. Full process:

    1. Copy the ActiveX file to C: Windows SysWOW64 DLL (not System32).
    2. Open quick command and register DLL: C: Windows SysWOW64> regsvr32
    3. Open the registry (enter regedit at a command prompt) and find the DLL name in HKEY_CLASSES_ROOT WOW6432Node CLSID . The DLL should find a key named HKEY_CLASSES_ROOT WOW6432Node CLSID GUID ! ! Copy the GUID to your clipboard.
    4. Create a new AppID string value that is often called in this key (and not in any of its subkeys). Set AppID to GUID (including curly braces) .A
    5. Create a new key: HKEY_CLASSES_ROOT WOW6432Node AppID GUID .
    6. In this new keychain, create an actual value named DllSurrogate . Leave the value blank.

    It is now desirable that an ActiveX object can only be created using PHP COM functions.

    In fact, this may be due to treasona functionality called “Session Nile Isolation”.

    As a result, Windows Server was converted to use COM 2003 in the service.Windows Server 2008 or newer is not used.And under Windows Vista, which is probably on the workstation side, COM cannot be used by programs running in the service.

    Click Start> All Programs> Accessories.Right click on Command Prompt and select Run as administrator.Enter either. (a) sfc / VERIFYONLY then press Enter.

    In Windows XP, Server 2003, and earlier versions of Windows, all services start with applications in session 0. This situation poses a security risk. Windows, when Vista, Windows Server 2008, combined with later versions of Windows, isolates operating system services in Session 5 and launches applications in other suites so that services are protected from application code hits.

    Don’t use COM on a website, as discussed in the previous Office article.

    Why is it showing Class not registered?

    The “Class not registered” error occurs when the DLL data file (.dll) is unregistered. A dynamic link library (DLL) file is an important file type that allows other programs to perform certain operations. Unlike executable programs (with the .exe file extension), it is difficult to run DLL files directly.

    Why does it say Class not registered when I try to open Spotify?

    The “Class not registered” error usually indicates an unregistered DLL file that is useful for the program to function properly. A dynamic link library (DLL) file is usually a file that contains code and therefore data that can be used by multiple programs at the same time and helps reduce memory consumption.
