VS 2017 SSRS Barcode do not work

I am new and just want to start using barcode with SSRS VS2017 but I get the following error after installing and follow the example of adding a barcode.

An error occurred during local report processing.
An error occurred during rendering of the report.
An error occurred during rendering of the report.
(Processing): extFactory != null

I could add the aspose barcode to the toolbox and see it on the design but when I click on previous it does not work.

Thanks for the screenshots.

Please make sure you have fulfilled system requirements as per the document:

Also, see the document for how to configure in VS.NET for your reference:

Hope, this helps a bit.

Thanks for the response. We are evaluating this product and before we can decide to buy it we need to make it work. I already did all what it required on the VS.Net set up and we have all the requirements. do I need to have this installed on the SSRS server to make it work locally on my VS? I just wanted to generate a simple report with a barcode.


Could you provide complete environment details (e.g OS, SQL Server with SSRS version, VS.NET and .NET framework version, etc.), we will check it.

Thanks for following in. The version I have are this one on my machine.

Microsoft Visual Studio Enterprise 2017

SQL Server Reporting Services 15.0.1659.0
Microsoft SQL Server Reporting Services Designers

And the company has this version on their servers. But we have not even try it there since we first want to have it working on VS locally.

Thanks for the environment details.

While we setup the environment which might take some time, are you using latest version of Aspose.BarCode for Reporting Services v19.8? If not, kindly try it from here as we did fix issues to work with VS2017/VS2019 and SSRS 2017 versions in it.

Yes that the version I am using …

Thanks for your confirmation and screenshot.

Please notice we have logged an investigation ticket with an id “BARCODEREP-84” for your issue. We will evaluate and look into your issue and figure it out soon.

Once we have an update on it, we will let you know here.

Any news, my company already bought the product and we are unable to use it. It would be greatly appreciated your help.


Well, we Investigated the problem with Aspose Barcode for Reporting Services in preview mode in VS2017/VS2019.

We found issue(s) with some run-time Reporting Services interfaces. We need to experiment and investigate Aspose Barcode code (internally) thoroughly and incorporate other enhancements. I am afraid, the process would take some time.

Once we have any new information, we will share it with you.

We are sorry for any inconvenience caused!

Current situation with Aspose.BarCode for Reporting Services (SSRS).

SSDT 15.9.3/VSIX 2.6.3(SSRS 15.0.1659.0) broken in preview mode with custom report items on system level. It must be fixed on Microsoft level.

VSIX 2.6.1(SSRS 15.0.1528.0) work after rebuilding Aspose.BarCode libraries with current SSRS libarires. This already done in BARCODEREP-88 and could be released in Aspose.BarCode 20.2 February release.

SSDT 15.9.2(SSRS 15.0.1395.0) works well with Aspose.BarCode 19.8 for Reporting Services.

SSDT 15.9.3

VSIX 2.6.3

SSDT 15.9.2

VSIX 2.6.1

As current workaround you could:

  1. remove VSIX 2.6.3 from Visual Studio Extensions
    Tools->Extensions and Updates->Installed->Microsoft Reporting Services Project->Uninstall
  2. install SSDT 15.9.2 which works well with Aspose.BarCode 19.8 for Reporting Services
    Previous releases of SQL Server Data Tools (SSDT) - SQL Server Data Tools (SSDT) | Microsoft Learn

In the end of February we will release Aspose.BarCode 20.2 version which will support VSIX 2.6.1. In this version (VSIX 2.6.1) must be fixed (be Microsoft release notes) problem with SSRS rebuilding libraries with new versions.

Thank you for the update. We managed to run our report with the barcode locally but with VS2010. The report on VS2017 cannot be executed locally but when we placed on our SSRS server they actually showed the barcoded correctly. So we will use it that way and wait for the fix at the end of the month to make it work 100% on VS2017.

So we will use it that way and wait for the fix at the end of the month to make it work 100% on VS2017.

It works with VS2017 now(SSDT 15.9.2). End of month fix will be for VSIX 2.6.1 (you have to reinstall it manually). Main difference between SSDT 15.9.2 and VSIX 2.6.1, VSIX can be installed slightly easier.

Last version SSRS(SSDT 15.9.3/VSIX 2.6.3) cannot be fixed in any way (VS2017/VS2019) because it is internal SSRS run-time library bug. We have to wait for fix from Microsoft.
