16-bit support missing??

[wingnux]

After updating to .59 (even after reverting to .5 I keep getting errors like this:

wingnux@wingnux:~/.wine/drive_c$ wine /media/cdrom/SETUP.EXE

Can anyone tell me what is it about and how to solve it? Thanks in advance!

It's a bug, kinda. Basically changes have been made in the sysctl file to protect the first 64k of kernel memory to stop future attacks.

You can revert the change by using:

sudo sysctl -w vm.mmap_min_addr=0

This *might* allow 16bit apps to work, it might not, but it will stop the complaining.

Thank you VERY MUCH! =)

Thank you very much for the solution. It indeed works. However, I want to ask does this setting change disables any other software to work in wine? What was the previously defined setting if I want to reverse it back?

By running that command it temporarily resets the sysctl setting to allow Wine to work. At the next reboot, it will go back to the original setting. Changing it temporarily or permanently will not affect any other software, but it may make your system very slightly less secure.

Installed flawlessly! THANK YOU!

Much appreciated. The only scary thing is how many windoze apps rely on that old 16-bit code slag. =)

This worked for me as well! Now I can install my six year old's Lego Land on his Edubuntu system. Thanks!
