What’s even worse are the installers that stop midway through the process to open up another installer.
One of the old AOL setup programs (4.0?) used to do this. I ran the installer, which got to maybe 75 percent complete and then froze while the IE upgrade installer ran, which in turn updated the freaking Win98 GUI, all without asking my permission* and all while the AOL progress bar sat there in the background, motionless.
- Probably in the EULA somewhere.
