Calibre Error: Failed to redirect stdout/stderr to NUL.

[TeddyTwice]

Hi guys,

this is my first thread ever, so please... be nice.

It's been two days since I'm getting the following error and trying to solve it:

Failed to redirect stdout/stderr to NUL. This indicates a corrupted Windows install.
You should contact Microsoft for assistance and/or follow the steps described here:

http://bytes.com/topic/net/answers/2...device-missing
No such file or directory (Error Code: 2)


I have tried pretty much everything I was able to find on the internet:

1) reinstalled

2) removed my Calibre settings (uninstall does not) located at C:\Users\username\appdata\roaming. Deleted the whole calibre folder.

3) checked the search path in case there is some other Python related folders ahead of the C:\Program files\Calibre2 that is the normal Calibre one.

4) installed an older version with my antivirus on hold

5) debugged in command prompt using the following command Code:
calibre-debug -g

6)checked NUL registry (as per indications in the URL: http://bytes.com/topic/net/answers/2...device-missing) - all seems fine

7) erased every little thing that has to do with calibre and installed from scratch

Nothing worked. Any ideas or suggestion will be very appreciated.

I'm running Win7, 64bit with Kaspersky.

@TeddyTwice - did you try the System File Checker (repair missing or corrupted system files) (← click)

If that doesn't fix it, try installing the 32bit version, it will install into Program Files (X86), it's OK to leave the 64bit version as is. The 32bit will use the existing configuration data that's already in %APPDATA%\

This means that the NUL file service in your windows install is not running/corrupted. calibre requires a working NUL service. There are two techniques for repairing it in that link. If neither works, then you will need to contact Microsoft for assitance or re-install Windows.

And which are the two techniques for repairing?

Technique 1:

i Tony,

As I understand, you get the following error when you try to build a
default Visual C++ .NET application.

"Null Device is Missing"

Based on my research and experience, please try the following steps on your
side: (I am using Windows XP Professional)

1. Go to the Start menu and select control Panel.
2. Select Administrative Tools.
3. Select Computer Management.
4. Select Device Manager.
5. Select the View Menu and the option for Show Hidden Devices
6. Expand the Non Plug and Play Drivers (Tree)
7. Scroll to the Null selection, right click, and select properties.
8. Make sure it is enabled and started.

Please try it and tell me the result.

and

Please perform the following step on your side after the step 7 on my
previous post.

Under Device Usage select "Use this device (enable)" and then Click OK.
I hope it helps.

Technique 2:

Please check the following registry key on your machine.

HKEY_LOCAL_MACHINE->SYSTEM->CurrentControlSet->Services->Null

The values of "Start" and "Type" should be "1" (Hex). If you want it, I can
a screen shot for your reference.
