**NEWS**

Successfully installed calibre-3.9.0.msi (Not the Portable app) to a hard disk. So, therefore, it seems likely that the code for the Portable (Or, the compiler of the Portable app code) changed from 2.x to 3.x. It is probably only observable on legacy hardware systems.

I am favoring the likelihood that the program which compiles the program changed during the time period of going from v2.85 to v3.0. That info should be available to Mr. Kovid Goyal.

There are, however, problems running the v3.9 program I just installed. The Welcome Wizard (Library folder set-up) ran and the UI did pop up properly the first time. However when trying to re-launch the program, I briefly see the splash image and Calibre shows up in the Windows Task Manager for a few seconds. But just as the splash image pops to the interface window the program (and process) disappears from the screen and Task Manager. There are no system event error logs.

I can launch the book-viewer.exe independently w/o a problem, but the main Calibre UI window will try to load for a couple of seconds and then the process vanishes.

Like I said earlier, either the coding or the compiler must have changed in a way that makes the overall installation or running of the program incompatible with my hardware. I don't think the OS is at fault.

Thanks to all who spent time thinking about this.
