Question from Customer:

Hi all,

Hope someone can help me out on this one. I read in another VeryPDF post that this error has been known to happen on Windows 2008 Server x64 and not so much on Windows 2003 server. I am running this on a Windows 2003 server SP 2 and I have confirmed that the directory 'C:\Windows\System32\config\systemprofile\Desktop' exists. So, what else could cause this problem?

https://www.verypdf.com/app/pdf-print-cmd/index.html

Here is the exact code that I am running (it is in C#) to invoke the pdfprint executable:

var psi = new ProcessStartInfo(printExe, args)
{
    ErrorDialog = false,
    WindowStyle = ProcessWindowStyle.Hidden,
    UseShellExecute = false,
    RedirectStandardError = true,
    RedirectStandardOutput = true,
    Domain = ConfigurationManager.AppSettings["DomainName"],
    UserName = ConfigurationManager.AppSettings["UserName"],
    Password = secPass,
};

var pdfPrint = Process.Start(psi);
if (pdfPrint == null)
{
    throw new ArgumentException("Failed to start Process.");
}

This code looks like it should invoke the pdfprint executable without issue. I am at a loss.

I am logging out the exit code, and it states that it exits with the code: 128

Any help on this issue is greatly appreciated.

Thanks!

Reply from VeryPDF:

Hello,

Thank you for your query. The issue you're experiencing seems related to permission restrictions in the default Local System User Account on your system. We recommend trying to use CmdAsUser.exe to run pdfprint.exe from an interactive user account, which should resolve the issue.

Here are the steps you can follow to resolve the problem:

1. Test PDFPrint in CMD:

First, ensure that pdfprint.exe can be executed manually via the Command Prompt (CMD).

• Open a Command Prompt window.

• Navigate to the folder where pdfprint.exe is located.
• Run the following command to print your PDF:

pdfprint.exe C:\verypdf\test.pdf

If pdfprint.exe runs correctly from the CMD window, it indicates that the user account you’re currently using (likely "Administrator") has proper permissions.

2. Download CmdAsUser.exe:

To resolve the issue, download CmdAsUser.exe from the following links:

• CmdAsUser Download
• CmdAsUser Zip File

After downloading, unzip the file to a folder (e.g., C:\verypdf).

3. Run PdfPrint via CmdAsUser:

Once you have CmdAsUser.exe set up, you can use it to run pdfprint.exe under the desired user account. Use the following command line:

CmdAsUser.exe Administrator . /p password /c "C:\verypdf\pdfprint.exe" -printer "192.168.1.10VeryPDFPrinter" C:\verypdf\test.pdf

In most systems, you may encounter error #1314, which indicates insufficient permission to switch the user account. If this occurs, please follow the instructions on the page below to solve the #1314 permission problem:

• Permission Error #1314 Solution

Once you’ve resolved the permission issue, you should be able to successfully launch pdfprint.exe via CmdAsUser.exe.

4. Update C# Code:

Finally, to invoke pdfprint.exe from your C# application, use CmdAsUser.exe instead of pdfprint.exe directly. Modify your C# code as follows:

printExe = "C:\\verypdf\\cmdasuser.exe";
args = "Administrator . /p password /c \"C:\\verypdf\\pdfprint.exe\" -printer \"192.168.1.10VeryPDFPrinter\" C:\\verypdf\\test.pdf";

var psi = new ProcessStartInfo(printExe, args)
{
    ErrorDialog = false,
    WindowStyle = ProcessWindowStyle.Hidden,
    UseShellExecute = false,
    RedirectStandardError = true,
    RedirectStandardOutput = true,
    Domain = ConfigurationManager.AppSettings["DomainName"],
    UserName = ConfigurationManager.AppSettings["UserName"],
    Password = secPass,
};

var pdfPrint = Process.Start(psi);
if (pdfPrint == null)
{
    throw new ArgumentException("Failed to start Process.");
}

This should resolve your problem and allow you to print PDFs from your C# code.
