I have downloaded a few versions of Revit 2019 from various websites, but none of them were working. So, as the due date of my project was approaching, I was getting more stressed. Eventually, I came across STFSoft Store and tried downloading it from there. Surprisingly, the software was working just fine. Thanks a lot, guys for saving me.
My engineering project due date was approaching and all of a sudden, my software has crashed. Thanks to STFSoft, I managed to find a legal version of AutoCAD LT 2017 and downloaded it without any issues.
