[eBook Viewer Crash report] - CBR file crashing

[Bilbotorm]

Hello

I would like to escalate a little issue as after some research ; I couldn't find any suitable answers.
I have been using Calibre for years now; and till recently; I was using simply the 32 bit version.

I switched to the 64 bits yesterday, and faced a strange issue : the ebook viewer executable is unable to read CBR files. CBZ files are fine, epub etc all ok; but CBR no. If I launch the 32 bit version it works like a charm.

Error message :
calibre, version 0.9.42
ERREUR : Impossible d’ouvrir le livre numérique: Erreur inconnue

Traceback (most recent call last):

MemoryError


Strange stuff : I have no memory issue (memtest launched just in case), I am under Windows 8 Pro 64 bits; i have like 5.5 go of free ram among 8 go available... So very strange issue.

I would appreciate any feedback here, till then, i'll stick to the 32 bit version.

Thanks !

PS : I saw some people faced this issue when converting CBR to ePub; but I am not; I am simply trying to view them (but this may be the same issue)

Some people's windows 64 bit machines have some security settings/software that causes various bits of calibre to crash. If you are one of those unfortunates, just use the 32 bit version.

Yes it most likely is the same issue. Viewing any ebook in calibre's viewer requires the book to be in a basic epub format, so if a book is not an epub then a quick and dirty conversion to epub is done first and that epub is sent to the viewer.

A work around exists if you have another CBR viewer on your computer you can go to Preferences - Behavior and uncheck CBR under the Use internal viewer for window and calibre will use whatever program is associated with CBR to view the book.

Thanks for the reply both of you.
Indeed i'll stick to the 32 bit version but i prefered to report the issue in case it could help (or if u needed me to conduct tests on some beta version or whatever)

Very strange issue (and the only one so far on 64 b version) hope it will get fixed someday

Thanks both
