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.

Hello Penn,

Could you please describe the issue so that we could understand the degree of "sameness"?

The project can't be created. Make sure you have .NET desktop development package installed in Visual Studio.

This message displayed when I try to create C++ addin in Visual Studio 2019.

I have already checked C++ Desktop Development when i installed VS 2019.

After installing VS 2017, it works now.
Maybe a bug in VS 2019?

Hello Penn,

As far as I understand there's a fix or workaround. Alas, due to an organizational issue I'll be able to provide any details on Monday only. I'm really sorry for the delay.
