about
QSAR Toolbox 4.1
QSARToolbox41Aug2017.R5.zip  2.44GB August 11, 2017

Important Note

The installation package is compressed using WinZip 17. Other applications might not be able to decompress the package as different applications implement the ZIP format differently. A free alternative that was tested with the installer package is the 7-Zip application. 7-Zip can be downloaded from http://www.7-zip.org/.

After downloading the zip package, please first decompress it and then start the installation from the resulting folder.
Do not run the installation directly from within the compressed file.
