Installing Arbortext Editor when Visual C++ 2015 Redistributable is installed
The Visual C++ 2015 Redistributable packages that were installed with Arbortext Editor 7.1 are not compatible with the Visual C++ 2017 Redistributable packages that are installed by Arbortext Editor 8.0.0.0.
When installing Arbortext Editor 8.0.0.0 on a machine on which Arbortext Editor 7.1 is already installed, use the following instructions to ensure successful installation of Visual C++ 2017 Redistributable:
Uninstall Visual C++ 2015 Redistributables before running the Arbortext Editor 8.0.0.0 installer. It is possible to use Arbortext Editor 7.1 with Visual C++ 2017 Redistributables.
If you do not uninstall, then you will have run the Arbortext Editor 8.0.0.0 installer three times: once to install the 32-bit Redistributable, again to install the 64-bit Redistributable and finally a third time to install Arbortext Editor.
