Hello,

This is my second full day with Add-in Express. I'm already impressed!

On day one I loaded Microsoft Office Home and Business 2019, Visual Studio 2019 and Add-in Express on a brand new Windows 10 computer.

I'm unable to create a new ADX XLL Add-in in C++. Although, I am able to build ADX XLL Add-ins in both BASIC and C#.

I get the following message when trying to create a C++ version:

Add-in Express for Microsoft Office and .NET
The project can't be created. Make sure you have .NET desktop development package installed in Visual Studio.

Am I missing a .NET development component that's specific to C++ or something else?

Thanks,

Hello John,

You should update your Visual Studio installation to add required components.

Thank you Andrei,

I've taken the following steps with unsuccessful results.

I modified my Visual Studio 2019 installation by checking all workgroups and checking all individual components. I ran the VS installation. I attempted to create an ADX XLL Add-in in C++, and received the same error message.

I removed my Visual Studio 2019 installation. I then reinstalled Visual Studio 2019 with all workgroups and all individual components (1,116 packages). I deleted the 'Add-in Express' folder from 'Program Files' and reinstalled 'Add-in Express'. I verified that I could still create XLLs in BASIC and C#. I attempted to create an ADX XLL Add-in in C++, and received the same error message.

What should I try next?

Thank you,

Hi John,

Thank you for the bug report. We will fix it as soon as possible.
Please keep in mind, Add-in Express based managed C++ projects support '/clr:safe' projects only. Also, you will not able to support both x86 and x64 platforms in one project.
