Calibre won't start

[Tarana]

I'm actually having the same problem as was originally stated. I've had absolutely no problems with 64 bit and suddenly, get a non responding white screen today.

Happily, I discovered, that in my case, I had downloaded the wrong version. I redownloaded the 64 bit and installed it and it works fine. However, it did not replace my icon or shortcut, so I have to delete and reset those.

The Libraries are already attached for either version because there is only ONE config file.

Something on yours got updated. Mine still works

I have done all the critical updates for W7 (Intel) and many optional (not Bing)

I don't have 'MS Office' products.
I have Nvidia graphics (low-mid end. Dell PSU to wimpy), Firefox,NP++,AVG free

I believe I have all updates, except my antivirus, set on manual, "notify me but do not install."

As long as Calibre is working with the 32bit version, I'm happy.

The attached screen shots are from Program Files, not Program Files (x86) which also has a Calibre folder. Let me know if I used the wrong one.

(I have been bit before with 'alternate HW' being mis-identified.)

@Tatezi - thanks a lot, interesting. What that tells us is that the ebook-edit program does not appear to be the 64bit version, even though its in the Program Files folder. If it was the 64bit version it should say so, at bottom left:-



But, the '[64 bit]' you see in the version number above does not come from the .exe file itself, so we can't be sure :-



I don't know for certain how calibre 'knows/thinks' that it's the 32bit or 64 bit install. One of my neurons suggests it may come from the python run-time environment.

Would you mind running calibre-debug - g at the command line against the two versions of calibre in Program Files (X86) and Program Files. Here's what I get, I've highlighted the salient differences - the fact that the 32bit is 2.25 and the 64 bit is 2.66 is immaterial - I think

32bit debug

C:\Program Files (x86)\Calibre2>calibre-debug -g
calibre 2.25 isfrozen: True is64bit: False
Windows-7-6.1.7601-SP1 Windows ('32bit', 'WindowsPE')
32bit process running on 64bit windows
('Windows', '7', '6.1.7601')
Python 2.7.9
Windows: ('7', '6.1.7601', 'SP1', 'Multiprocessor Free')

64 bit debug

C:\Program Files\Calibre2>calibre-debug -g
calibre 2.26 [64bit] isfrozen: True is64bit: True
Windows-7-6.1.7601-SP1 Windows ('64bit', 'WindowsPE')
('Windows', '7', '6.1.7601')
Python 2.7.9
Windows: ('7', '6.1.7601', 'SP1', 'Multiprocessor Free')

Means another board/device that shares common roots (chips) or failure of a manufacturer to assign a unique (USB) ID

to wit. Turtlebeach Montego sound card used a custom Dolby Surround driver.
M$ kept trying to install a standard driver update because they detected the chip (part of the set) Turtlebeach used

theducks...Thanks for taking the time to explain to me. I understand now. Much appreciated.
