A little help with a new error message?

[Randy]

Just installed 0.9.30 and now when attempting to open a book (that I had opened successfully in the past) Calibre throws the following error:

[Error 5] Access is denied: u'C:
\\Users\\Windows7\\AppData\\Local\\Temp\\calibre_k smazn\\egatqy_ebook_iter'

Here's what got copied to the clipboard:

Traceback (most recent call last):
File "site-packages\calibre\gui2\viewer\main.py", line 40, in run
File "threading.py", line 763, in run

WindowsError: [Error 5] Access is denied: u'C:\\Users\\Windows7\\AppData\\Local\\Temp\\calib re_qkxlqy\\4af5ur_ebook_iter'



This machine is running Windows 8 64-bit, running as admin. Is there a clue in the above?

Many thanks!

Not entirely sure what's going on there, I also have the same issue.

Is the Ebook cover displayed? Also, are you able to view it in it's folder by opening it manually?

That message says you do not have FULL access to the/your systems TEMP folder.
Something is blocking access (your anti-whatever )

Just wondering... when you say running as admin do you mean that you are right clicking on calibre and saying "Run as adminisitrator"?

If so I really don't understand the need for that....

@Randy Does the folder C:\Users\Windows7\AppData\Local\Temp\calibre_k smazn exist

If so what's in it ?

Is this a new computer with factory installed Win8 or is it a 'pre-loved' computer that's been upgraded to Win8

@Dullahir - what OS are you using ?

Something on your computer is preventing calibre from accessing its own temporary files. Most
likely the permissions on your Temp folder are incorrect. Go to the folder
C:\\Users\\USERNAME\\AppData\\Local in Windows Explorer and then
right click on the Temp folder, select Properties and go to
the Security tab. Make sure that your user account has full control
for this folder.

Alternately, you can run calibre as Administrator, but doing so will cause
some functionality, such as drag and drop to not work.

Finally, some users have reported that disabling UAC fixes the problem.

@Dullahir - the cover is indeed displayed

@PeterT - the account I use has full admin privileges

@BetterRed - C:\Users\Windows7\AppData\Local\Temp\calibre_k smazn does NOT exist - and I think it would be a file rather than a folder. The computer was factory installed with Windows 7 that I have upgraded to 8 not long after it was released. Previous versions of Calibre ran fine - it's only upon upgrading Calibre to 0.9.30 that this problem arose.

@kovidgoyal - Permissions for the temp folder appear to be correct. Running the app as administrator seems to solve this particular problem, but that's not really a good solution.

Thanks for all the suggestions, but the problem remains unresolved.

There is nothing in 0.9.30 to cause this, the problem is specific to your computer. However, feel free to downgrade to a previous release, if you want to, instructions for getting previous releases are present on the download page.

In trying to install an older version, an error popped up at the end of the install process that I remember appeared when I installed 0.9.30. I dismissed it at the time, as the program seemed to have installed correctly. Now I'm thinking that maybe this is the source of my problem:

'There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor.'

Does this ring any bells?

Yes, that tells me that something on your computer is blocking access to the temp folder, as I said before.

Thanks to everyone.

My first reaction would be to wonder why a User with Windows 7 in its /User path is being pointed at when you now, as I understand it to be, have a Windows 8 PC?

If something is incorrect there then a permission problem would result. Windows 8 installs over Windows 7, in my experience, always create a new clean User path.

This may have come about, for example, if you have pointed Calibre to a backup User folder, archiving the old Windows 7 user account, that was created by the Windows 8 install.

If looking at the User folders does not produce an obvious answer to that as to a problem or not, then a test would be to create a new user account and install Calibre with that account and see what happens.

[BetterRed]

Ditto what AnotherCat said

And what is the value of the TEMP environment value

And what are you logged in as ?

Hi everyone. I am experiencing the same issue as Randy. I have a new Windows 8 machine, moved my library from the old machine to a custom folder, installed Calibre and it went fine. Today I upgraded to the latest version and when I try to download metadata for a book I get the message:
calibre, version 0.9.33
ERRORE: Scaricamento non riuscito: Scaricamento delle copertine non riuscito, fai clic su "Mostra dettagli" per informazioni.

Traceback (most recent call last):
File "site-packages\calibre\utils\ipc\simple_worker.py", line 210, in main

WindowsError: [Error 5] Accesso negato: u'C:\\Users\\Andrea\\AppData\\Local\\Temp\\calibre _8ljl95\\8e4wfy_single_metadata_download'

I would like to follow AnotherCat's and BetterRed's suggestions, but I am not sure I understand them. Could you please explain a bit more?

Best, Andrea

Hi everyone. I ran into this suggestion on another webpage, and that solved the issue:

"I ran into this issue, too. Alexey Ivanov's response didn't quite help me, but it did, however, inspire me to investigate C:\Users\x\AppData\Local\Temp.

As usual, error messages were only half-useful. In my case, the DLL wasn't missing--the installer didn't have permissions to access the folder. I didn't try running the installer as an administrator--this didn't make sense to me considering I was already using an admin account and would have expected UAC to handle privileges elevation. Anyway, like many things in Windows, this whole thing is a bit of a mystery to me.

Nevertheless, after going to Properties > Security on the C:\Users\x\AppData\Local\Temp folder and giving that Everyone the Full control permission, installers that previous had been failing now worked! Hooray! Since Everyone already had Read and Write access, I suspect that Full control also added a necessary Execute permission.

What I wonder, now, is how this happened in the first place, and what the correct permissions on this directory are supposed to be."
