The above link goes to the zip file that contains the executable file itself, the help file, and the license statement for autoruns.
Autoruns delineates every thing that is loaded when Windows starts. It gives you the option of searching through the entire list - which may be incredibly lengthy - using control-F for find, and function key three in order to continue looking for more iterations of your search.
Un-Checking the box on the extreme left hand side prevents that particular application from loading when Windows next starts.
If you use this application, be certain of exactly what you are un-checking.
It is entirely possible to uncheck an application that is actually mandatory for Windows to run.
This results in Windows not being able to run and sometimes the problem not being fixed with System File Checker .
By the way, I just finished running Windows System File Checker [through an administrative command prompt window ] just to be sure, and no errors were found.
Okay… Next I created a simple Windows text file, opened up the sixty-four bit version of Calibre, and dropped the file onto a book. The program immediately froze and the usual window came up. Interestingly enough, the files appeared on my desktop, which was theoretically immediately underneath the Calibre 64-bit window. They were moved from their original location, to the underlying desktop.
I use total Commander in place of the Windows Explorer. Although that should not make any difference.
Now going to try creating the temporary directory and then create the environmental variable. Will report back when I have done this.
Okay… I followed the directions for creating system variables in Windows. I created a variable with the name of CALIBRE_TEMP_DIR
I made the variable value for that
C:\CalTemp
And then I also separately tried using the variable value
C:\CalTemp\
[I did it both ways, since I was not sure whether or not you needed a trailing…\… In order to properly represent the directory] Both methods yielded the same result. I did not do this in the safe mode.
I don't know if I have to tell Calibre somehow what to set the value for CALIBRE_TEMP_DIR within the program itself. Or does Calibre simply look to existing variables that preexist in Windows?
I guess I'm not quite understanding if I need to tell the Calibre 64-bit program anything specific about this particular variable. I don't seem to find the CALIBRE_TEMP_DIR variable when I search for it under tweaks.
In any event, the 64-bit program locked up per usual.
I will await further instructions on this.
Okay… cybmole… Thank you very much for making the suggestions! Here is how they have worked for me.
Your first suggestion – and by the way a very good suggestion – About going to a prior restore… I cannot do this easily. the change probably occurred at some point over a three – to – six month period and I was not – during those somewhere between three and six months – doing anything with the 64-bit version other than reading existing books, with the beautiful internal reader.
Therefore I have no idea when the conflicting program or condition arose.
My computer is set to do an automatic backup to a separate hard drive at 2 AM every morning on a daily basis. There are well over a hundred backups over that three-month period. I have no idea which backup if any, would work. It may well be that the problem occurred five months ago.
If there is no other way, then I will try going back six months, doing a complete system restore, and seeing whether or not Calibre sixty-four bit runs normally. I'm dragging my feet with that because then I have to restore email databases etc.
I have run ccleaner a couple of times since the problem occurred, but there was no difference in performance.
As far as doing a clean install of the 64-bit Calibre, I have done exactly that. I renamed my existing Calibre library to something else. Next I uninstalled the 64-bit version of Calibre using the standard Windows uninstall, then did a clean install of the 64-bit version, and when I attempt to add books to the now empty library, the program locks up.
This occurs by the way in BOTH the safe mode, and the normal Windows mode.
I uninstalled the Logitech driver for keyboard and mouse, but since it did not seem to make a difference I'm planning on reinstalling them at some point later on today.
I am not running roboform.
I removed SUPERAntiSpyware from the system completely using the normal Windows uninstall. This program was running earlier when the problem first occurred but has since been uninstalled.
I can randomly create, rename, delete, and manipulate folders at will. In fact this is done on a daily basis using Photoshop, Lightroom, and Bridge.
Many, many thanks for taking the time to read this and make suggestions!
