2016 max Installation issues on Win 11 25H2

[Danny]

I've been running 2016 max / Vray on win 11 installed as an in place update from win 10 for at least 2 years now. I did a fresh win11 25H2 installation, now the max installers will not unpack the exe files. When I launch the 001_001.sfx.exe it prompts the unpacker, then just shuts off. I tried shutting off all anti virus and fire wall .. VPN exe, compatibility mode, nothing seems to work, . I was able to install  win 10 on a Virtual drive and the Installer worked, so its works, but obvious not an ideal work environment. Anyone have any ideas?

I had this issue getting Map 3D 2026 installed, Map 3D 2025 installed fine and all the other AutoCAD 2026 and Toolsets installed.

 

Ended up getting Autodesk to install it, since IT didn't want to go through everything. Basically did a bunch of registry resets.

 

You might try installing the latest version's free trial just to see if it installs okay.

thks for the reply, that did not work, the 2026 trial version installed without issue. I posted this issue in the autodesk forum, I looked today the moderator removed it
