Hello Vic. Just to let you know, I'd successfully installed the IRIS!!
The problem was on the path thar I was trying to install it. I intended to install it on a partition NTFS (I have a Dual Boot into my machine) and it shoud help me to code in both the systems.

So I'd choosed other path Into my Linux partition and just use the NFTF partition to all my database, with this I was able to install the IRIS on Ubuntu.

Thank you so much for your time.

Hello Vic,

I'd tried to do the steps as the documentation said about the temporary path and I'd tried to install from other directory as well.

Both had the same result, and the log file "/mnt/WinData/InterSystemsLinux/mgr/messages.log" wasn't created.

I guess there's no permissions issues, but i'll check on it again.
