Installer not compatible error

[tshirey]

I have a server I am trying to install this package on.
MS Windows Server 2019 Datacenter
10.0.17763 Build 17763
Microsoft SQL Server 2019 (RTM-CU5) (KB4552255) - 15.0.4043.16 (X64)
Microsoft Visual Studio Enterprise 2019 Version 16.6.5
Microsoft ,Net 4.8.03761

When I load the solution I get an error that MultipleHash2008 is not compatible with .Net 4.6.1
and then when I get to the solution explorer I see that the MultipleHashInsterx32 and MultipleHashInsterx64 show as "incompatible"

How do I install this package?

Multiple Hash 2008 needs ,Net Framework 3.5.

Are you trying to compile the software, as opposed to installing the MSI?
If trying to compile the software, you need to have the various framework versions available in Visual Studio for SQL Versions 2008 through 2022.
That is .Net Framework versions (or targeting capability):
3.5
4.0
4.5
4.6
4.6.2
4.7.2

And the DLL's that are referenced for all these versions.
eg.
Microsoft.SqlServer.Dts.Design.dll
Microsoft.SQLServer.DTSPipelineWrap.dll
Microsoft.SqlServer.DTSRuntimeWrap.dll
Microsoft.SqlServer.ManagedDTS.dll
Microsoft.SqlServer.Management.IntegrationServicesEnum.dll
Microsoft.SQLServer.PipelineHost.dll
