[@Inacio] Hi Inacio, I am sorry you are experiencing difficulty during the download.
The Ability website FAQ suggests:
“Ability use a standard Microsoft bootstraper called setup.exe to manage the download of the actual installer. If something goes wrong when setup is downloading or executing the installer, then a message similar to “cannot find MSI” will be displayed.
“The usual cause is too many temp files – try using Windows Disk Cleanup utility to delete temporary files and temporary internet files. To run this, type “Disk Cleanup” in the Windows search box.”
This seems a little simplistic but worth a try.
Best wishes for the New Year!
