Hello,
I have a trouble with pdf2txtocr.exe utility.
This utility is crashing when it is launched from a Windows service in Windows Server 2008 x64 or Windows 7 x64.
The exception code: C0000005 ACCESS_VIOLATION appears during execution of the "pdf2txtocr.exe" utility when launched by service for x64 computer. 

Please note that pdf2txtocr.exe works correctly under Windows Server 2003 x84, in the same conditions: launched from a Windows service.

I have found and validate your solution in our test environment: 

Call PDF to Text OCR from Web or Windows Service
 
It does not solve the issue: pdf2txtocr.exe is still crashing. 


What can be a cause of such failure ?
I am looking forward to your answer.

Thank you.

Peter

This problem is caused by permission of Windows Service account, we suggest you may use cmdasuser.exe to launch pdf2txtocr.exe from an interactive user account, cmdasuser.exe can be downloaded from following web page,

 

http://www.verydoc.com/exeshell.html

 

CmdAsUser Administrator . /p Password /c "C:VeryPDFpdf2txtocr.exe" C:VeryPDFtest.pdf C:VeryPDFout.txt

 

if you can run above command line in CMD window by manual correctly, you can call above command line from Windows Service without any problem too.

Remark:
You may encounter Error 1314 in some Windows systems when you switch between user accounts, this is caused by permission setting, please by following steps to solve this 1314 Error,

ERROR 1314:
~~~~~~~~~~~~~
1314 A required privilege is not held by the client. ERROR_PRIVILEGE_NOT_HELD
~~~~~~~~~~~~~

To resolve this issue:
1. Click Start, click Run, type "secpol.msc", and then press ENTER.
2. Double-click "Local Policies".
3. Double-click "User Rights Assignment".
4. Double-click "Replace a process level token".
5. Click "Add", and then double-click the "Everyone" group
6. Click "OK".
7. You may have to logout or even reboot to have this change take effect.

Please refer to following two screenshots to understand above steps,

Please look at following page for the details about ERROR 1314,

As I posted above, I already followed to your recommendations:
CmdAsUser was executed correctly, but pdf2txtocr.exe was failed in the same place.

Anyway, thank you for quick response.
