AMD Ryzen 5 3400G with Radeon Vega Graphics, 3.70 GHz
64,0 GB RAM
Windows 10
I've been using the 64-bit version for years. I tried to install a 32-bit version, but the behavior is the same, the initial installation percentage bar goes to the end (100%), closes as if it were to start the installation, but nothing else happens. Does not create any installation folder. As a security, I use the Microsoft Windows Defender, the protection app that is already included in Windows 10.
I uninstalled the MC27 that was working on my computer until today (I did the "MC Library Backup" before, it is attached, but can't even install the MC30 (or MC27, again).
Also allowed exceptions in Windows Defendender for JRiver Folder and files.
