Try & Decide did a PC restart

Hello,

I just started try and decide to do a testinstallation of a program.
The installation was not finished yet when Acronis was showing a message that there is not enough space at my harddisk and the program want to do restart.

There were 2 options to decide from, keep it or not. But before I finished to read the message Acronis did the restart.
Why the program is doing such crazy things. I could not do anything to prevent the restart or do it later.

There were several programs open and Acronis did not asked me if I want the restart now.

kind regards

Andreas
