Conflicts between different versions of DLL files can also lead to problems in your applications and incorrectly registered DLL files can make Windows components such as Windows Update fail to work completely. When problems strike, you need to take control of the DLL situation on your PC. Using the 3-step plan outlined in this article, you can fix most DLL problems very quickly.

Because DLLs are can conflict shared between applications, this can cause problems, as an application on your system may only work with a certain version of a DLL file. If a different version of a DLL is installed on to your system, this can lead to DLL version conflicts, which result in some of your applications not working. Process Explorer is a tool from Microsoft that can help you Process resolve these problems by examining every aspect of a Explorer running program, including the DLLs it is using. Apart from running process names, extensive information is displayed such as the load on your CPU (processor load), a description of each running application and the name of the developer of each application. You can download Process Explorer from the Downloads area of the Windows Advisor website, www.windowsadvisor.co.uk . Selecting the name of a process and clicking View > Show Lower Pane will display all of the DLLs loaded by that process, which is essential information when you are trying to troubleshoot application DLL errors. When you choose to show the lower pane of the window, you can use the DLL button in the menu bar (shown as a yellow cog icon) to easily switch between DLL view and Handle view. DLL view is the most important, as it shows the open DLLs. The display of application dependencies and DLLs is particularly important for error analysis purposes. Here, Process Explorer helps in two ways: The Windows Advisor April 2018 19 D496.qxp_April 2018 28/02/2018 13:23 Page 20 D 496/6 DLL Error Troubleshooting Check which 1.

More non-scary details are in Privacy Policy. Stay safe! When Windows is not able to start even in Safe Mode, then most probably there are some errors or missing files on your hard disk that prevent Windows Vista or 7 from starting correctly. Repair Your Computer is a set of tools for recovering from Windows such errors and it is available on Windows installation DVD. Windows 7 users can also create a System Repair Disc, or borrow one from friends - as long as the hardware architecture (32-bit/x86 or 64-bit/x64) matches. Here are some troubleshooting steps to try before using Repair Your Computer: Last Known Good Configuration often solves booting and stability problems after installing software, drivers, or messing with Registry entries. Always boot to Safe Mode at least once - this often repairs corrupted file system and essential system files. If Windows is able to boot, use System File Checker and icacls.exe to repair corrupted system files. While Windows is running, use free WhoCrashed for determining BSOD (Blue Screen Of Death) causes. Also, Reliability Monitor might reveal faulty drivers or software. System Restore can help reverting back to a state when your computer was running normally.

  • Cxspectra How to Fix Hasp Com Windows.Dll Is Missing / Not Found Error Messages
    CXSpectra How To Fix Hasp_com_windows.dll is Missing / Not Found Error Messages Overview of Hasp_com_windows.dll What Is Hasp_com_windows.dll? Hasp_com_windows.dll is a type of DLL file associated with HASP SRM Assembly for Microsoft .NET developed by Windows Software Developer for the Windows Operating System. The latest known version of Hasp_com_windows.dll is 3.5, which was produced for Windows. This DLL file carries a popularity rating of 1 stars and a security rating of "UNKNOWN". What Are DLL Files? DLL ("dynamic link library") files such as hasp_com_windows.dll are small programs, similar to EXE ("executable") files, which allow multiple software programs to share the same functionality (eg. printing). For example, let's say you are running Windows and editing a document in Microsoft Word. The DLL file that controls printing does not need to load unless it's function is needed - eg. you decide to print your document. When you select "Print", Microsoft Word calls the printer DLL file, and it is loaded into memory (RAM) at that time. If you want to print a document in another program, Adobe Acrobat for example, that same printer DLL file will be used as well. Why Do I Have DLL Errors? Because they are shared files, DLL files exist outside of the software application itself. Although this provides many benefits for software developers, this separation also provides an opportunity for problems to occur. Quite simply, if Windows cannot properly load your hasp_com_windows.dll file, you will encounter an error message. Please see "Causes of hasp_com_windows.dll Errors" below for more information.

    Distributing our Instrumentation ActiveX Controls You only need to copy and register the OCX files for those components that you program uses on the destination computer to successfully distribute our ActiveX components. You can follow one of the following methods to distribute our components. Our ActiveX components have no dependencies on any other operating system files. WARNING!: under our license agreement, you are not allowed to distribute the LIC (license) files that are associated with our ActiveX components to your end user's computers. Also, there is generally no need to distribute the associated TLB files. Just distribute the OCX files. Manual Registration This method involves a manual installation of your compiled software and our ActiveX components. This is generally used in situations where you are only distributing your application to a few number of computers. 1. Copy the OCX files that your program requires (Example: copy the "iStripChartXComponent.ocx" and "isAnalogLibrary.ocx" files if your program uses our Strip Chart and Analog Gauge components) to the target computer's system directory. This is usually "C:\WINDOWS\SYSTEM" for Windows 95/98 and "C:\WINNT\SYSTEM32" for Windows NT/2000 systems. 2.
