OR Tools on Windows

[Kevin Malysiak]

I've installed on WIndows 11 (Home) the as per the instructions. I'm able to compile one of the samples of interest. However, when I attempt to execute, there is a library not found. See below.

Any advice appreciated.

Thanks.

Kevin.

As usual, most likely missing visual studio redistributable librairies.

Hi,

Thanks for your note.

I'm pretty sure I installed the required library.

I followed the installation instructions at https://developers.google.com/optimization/install/java/binary_windows.

In the section on Prerequisites, there is a link to download the redistributable libraries. The downloaded file was called VC_redist.x64.exe. I installed it.

Then, when I check in the settings, that is Settings -> Apps -> Installed Apps, I see Microsoft Visual C++ Redistributable (x64) - 14.40.33816 is installed.

Unless this is the wrong file?

Settings-> Apps -> Installed Apps also shows some earlier versions of this library installed. Could that be the problem?

Thanks.

Kevin.

Sorry that should be ...

 Microsoft Visual C++ 2015-2022 Redistributable (x64) - 14.40.33816
