Received 2 versions in the GAC when installing infragistics which disrupts builds in Visual Studio


I have installed Infragistics 15.1 (Windows Forms) (Infragistics Professional 2015.1), however I have 2 versions in my GAC and is now causing build failures when trying to build applications on Visual Studio 2019. Before I used to receive only one version in the GAC and there would be no issues.

This is the filepath: C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Infragistics4.Win.v15.1

The 2 folders that appear are: v4.0_15.1.20151.1000__7dd5c3163f2cd0cb AND v4.0_15.1.20151.2230__7dd5c3163f2cd0cb

Is there a way for me to install infragistics with only one version being instaled in the GAC?

Kind Regards,

    Version .100 is the base version, while .2230 is a service release which should have upgraded the base version.

    Did you use the platform installer to apply the service release?

    I have tested the insall of 2015.1 with the platform installer, and I only get the .2230 in my GAC folder.

    Can you please re-install with the Platform Installer and let me know if you still experience issues.
