AxInterop.AcroPDFLib.dll: A .NET Interop Assembly for Adobe Acrobat PDF Reader ActiveX Control



Axinterop Acropdflib Dll 64 Bit Download: What You Need to Know




If you are a .NET developer who wants to display and manipulate PDF files in your C# WinForms application, you might have encountered the AxInterop.AcroPDFLib.dll file. This file is a Microsoft .NET interop assembly that allows a .NET application to communicate with the Adobe Acrobat PDF reader ActiveX control. However, you might also have faced some issues with this file, especially if you are using a 64 bit operating system. In this article, we will explain what AxInterop.AcroPDFLib.dll is, why it causes problems on 64 bit OS, and how to fix them.

What is AxInterop.AcroPDFLib.dll?




AxInterop.AcroPDFLib.dll is a wrapper file that enables a .NET application to use the AcroPDFLib.dll file, which is the Adobe Acrobat PDF reader ActiveX control. The ActiveX control provides functionality for displaying and manipulating PDF files within a .NET application. For example, you can use it to load, print, zoom, rotate, or save PDF files.


To use the ActiveX control in your .NET application, you need to add a reference to the AcroPDFLib.dll file and create an instance of the AxAcroPDF class. You also need to add the AxInterop.AcroPDFLib.dll file to your project, which is generated automatically when you add the reference to the AcroPDFLib.dll file. The AxInterop.AcroPDFLib.dll file contains the metadata and the code that allows your .NET application to interact with the ActiveX control.


Why does AxInterop.AcroPDFLib.dll cause problems on 64 bit OS?




The main reason why AxInterop.AcroPDFLib.dll causes problems on 64 bit OS is that there is no 64 bit version of this file or the AcroPDFLib.dll file. The ActiveX control is only available as a 32 bit component, which means that it cannot be loaded by a 64 bit process. If you try to use the ActiveX control in a 64 bit .NET application, you will get an error message saying that AxInterop.AcroPDFLib.dll was not found or that it is not a valid Win32 application.


This problem occurs because by default, a .NET application is compiled with the target platform set to "Any CPU", which means that it can run on either 32 bit or 64 bit OS. However, when you run your application on a 64 bit OS, it will run as a 64 bit process and try to load the 32 bit ActiveX control, which will fail.


How to fix AxInterop.AcroPDFLib.dll errors on 64 bit OS?




There are two possible ways to fix AxInterop.AcroPDFLib.dll errors on 64 bit OS:


  • The first way is to change the target platform of your .NET application from "Any CPU" to "x86". This will force your application to run as a 32 bit process on any OS and load the 32 bit ActiveX control without any issues. To do this, you need to follow these steps:



  • On the "Tools" menu, click "Options".



  • Check "Show all settings".



  • Expand "Projects and Solutions" and click "General".



  • Check "Show advanced build configurations".



  • Click "OK".



  • On the "Build" click "Configuration Manager...". (Add it if it isn't there)



  • In the "Active solution platform:" drop down, click "".



  • In the "Type or select the new platform:" drop down, click "x86".



  • Click "OK".



  • Click "Close".



  • The second way is to use an alternative library or component that can display PDF files in a .NET application and that supports 64 bit OS. For example, you can use Ghostscript.NET, which is a GPL library that can be used to display PDFs inside a 64 bit .NET WinForms application. You can also use other third-party libraries or components that offer similar functionality and compatibility.



By following either of these methods, you should be able to fix AxInterop.AcroPDFLib.dll errors on 64 bit OS and use PDF files in your .NET application without any problems.


Conclusion




AxInterop.AcroPDFLib.dll is a .NET interop assembly file that allows a .NET application to communicate with the Adobe Acrobat PDF reader ActiveX control. However, it can cause problems on 64 bit OS because there is no 64 bit version of this file or the ActiveX control. To fix these problems, you can either change the target platform of your .NET application to x86 or use an alternative library or component that can display PDF files in a .NET application and that supports 64 bit OS.


We hope this article has helped you understand what AxInterop.AcroPDFLib.dll is and how to fix its errors on 64 bit OS. If you have any questions or comments, please feel free to leave them below.

Axinterop Acropdflib Dll 64 Bit Download: Benefits and Drawbacks




Using AxInterop.AcroPDFLib.dll to display PDF files in your .NET application can have some benefits and drawbacks, depending on your needs and preferences. Here are some of them:


Benefits




  • Using AxInterop.AcroPDFLib.dll allows you to leverage the features and functionality of the Adobe Acrobat PDF reader ActiveX control, which is a widely used and trusted component for working with PDF files.



  • Using AxInterop.AcroPDFLib.dll does not require you to install any additional software or components on your system, as long as you have the Adobe Acrobat PDF reader installed.



  • Using AxInterop.AcroPDFLib.dll gives you a high level of control and customization over the appearance and behavior of the PDF viewer in your .NET application. You can use various properties and methods of the AxAcroPDF class to load, print, zoom, rotate, or save PDF files.



  • Using AxInterop.AcroPDFLib.dll is relatively easy and straightforward, as you only need to add a reference to the AcroPDFLib.dll file and create an instance of the AxAcroPDF class in your .NET application.



Drawbacks




  • Using AxInterop.AcroPDFLib.dll can cause compatibility issues on 64 bit OS, as there is no 64 bit version of this file or the ActiveX control. You will need to change the target platform of your .NET application to x86 or use an alternative library or component that supports 64 bit OS.



  • Using AxInterop.AcroPDFLib.dll can cause performance issues on your .NET application, as the ActiveX control is a heavy component that consumes a lot of memory and CPU resources. You will need to optimize your code and ensure that you dispose of the AxAcroPDF object properly when you are done with it.



  • Using AxInterop.AcroPDFLib.dll can cause security issues on your .NET application, as the ActiveX control can execute malicious code or access sensitive data from your system. You will need to ensure that you only load trusted PDF files and that you configure the security settings of the ActiveX control appropriately.



  • Using AxInterop.AcroPDFLib.dll can cause licensing issues on your .NET application, as the ActiveX control is a proprietary component that requires a license from Adobe. You will need to ensure that you co
