Installer throwing MissingTargetFrameworkException exception

[nathan-alden-sr]

I downloaded the installer from http://pgfoundry.org/frs/download.php/3797/Setup_Npgsql-2.2.3.0-r2-net45.exe. I chose to install all options. The installer fails to install the VS 2013 extension with this message:

Install Error : Microsoft.VisualStudio.ExtensionManager.MissingTargetFrameworkException: The extension 'NpgsqlDdexProvider' requires a version of the .NET Framework that is not installed.

Of course, my machine has .NET 4.5 installed, as well as .NET 4.5.1 and .NET 4.5.2. I am running Visual Studio Ultimate 2013 only. I suspect this may have to do with me having .NET 4.5.1 and .NET 4.5.2 installed. Perhaps the installer needs to be more lenient with its required .NET Framework versions.

Please let me know if I can somehow help resolve this issue as it is preventing me from creating PostgreSQL data sources in VS 2013.

Here is the full log file:

Hi. Thanks for trying it! I remember that the ddex installation ran well in those days...

Today I have encountered the same problem as you have reported, when I install ddex support. I'll check it.

Hi. @nathan-alden

The problem is fixed, and new setups are avail:

Setup_Npgsql-2.2.4.1-net45.exe (Vs2013/Vs2012) https://drive.google.com/file/d/0BzIsP2o582nbVHl5all5UklidWM/view?usp=sharing

Setup_Npgsql-2.2.4.1-net40.exe (Vs2010) https://drive.google.com/file/d/0BzIsP2o582nbM0ZhelU5UG90bWc/view?usp=sharing

These setups are built through my private branch Branch_v2.2.4.1_with_setup. kenjiuno/Npgsql@2e34d46fbaf58853e487b0e678bea5e9d9174cdb

I'll be glad if newer setup is updated at release section. https://github.com/npgsql/npgsql/releases/tag/v2.2.4.1

Thanks kenjiuno

I'll be glad if newer setup is updated at release section.

Done.

Thank you very much @kenjiuno for your help with those installers! :)

Thank you for being so responsive to this issue. Your fix worked on my machine. Keep giving us .NET developers a reason to use PostgreSQL! :+1:
