How to run doc2pdf.exe which included in docPrint Pro from Web Service?

Hello We are planning to use your component for unattended documents processing on ~50 workstations. The (doc2pdf) application will be invoked by a windows service. The process will be unattended, as such we would like to know about potential pitfalls e.g. run time errors. We know you have server license, but that won't work for us - the processing will be distributed (geographically).

Thank you.

--------------------------------------
You need run doc2any.exe from an interactive user account instead of default system user account, please refer to the example #6 and example #7 at following web page,

Example 6: Run conversion via "docPrint_Service.exe" application,

Please by following steps to run conversion via "docPrint_Service.exe" application,

1. Please login your server via Remote Desktop under Administrator user account (or other user accounts who own Administrator right),

2. Please run "docPrint_Service.exe" application,

"C:\Program Files\docPrint Pro v5.0\docPrint_Service.exe"

3. Call RunCmd() method to deliver a command line to "docPrint_Service.exe" application,

PHP example,
<?php
    $com = new COM("DocPrintCom.docPrint");
    $com->docPrintCOM_Register("XXXXXXXXXXXXXX","VeryPDF.com Inc.");
    $com->RunCmd("-i https://www.verypdf.com -o C:\\test\\output.pdf -* XXXXXXXXXXXXXX -d -O 2 -s ShowHTMLStatusBar=1 -l 10000", 0);
?>

VB example,
Private Sub Command1_Click()
    Set docPrint = CreateObject("DocPrintCom.docPrint")
    nRet = docPrint.docPrintCOM_Register("XXXXXXXXXXXXXX", "VeryPDF.com Company")
    nRet = docPrint.RunCmd("-i https://www.verypdf.com -o C:\output.pdf -* XXXXXXXXXXXXXX -d -O 2 -s ShowHTMLStatusBar=1 -l 10000", 0)
    MsgBox "Return value = " & Str(nRet)
End Sub

4. Close Remote Desktop and leave this user logged in.

*Please Notice: After you reboot the server, you need login your server via Remote Desktop with this user account ("docPrint_Service.exe" was installed inside this user account), and close Remote Desktop, leave this user logged in, when you call RunCmd() function, the conversion will be executed from this user account automatically.

Example 7: Run conversion inside an interactive user account from service or web applications,

Please by following solution to run document conversion inside an interactive user account,

1. Please add "Everyone" user account to "C:\Program Files\docPrint Pro v5.0" folder and sub-folders, give "Full Control" permission to "Everyone" user account,

2. Download CmdAsUser.exe from following page,

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

You can also download it from following URL directly,

3. Run following command line to test CmdAsUser.exe application,

C:\test\CmdAsUser.exe Administrator . /p password /c "C:\Program Files\docPrint Pro v5.0\doc2pdf.exe" -i http://www.google.com -o C:\test\out.pdf

C:\test\CmdAsUser.exe Administrator . /p password /c "C:\Program Files\docPrint Pro v5.0\doc2pdf.exe" -i C:\test\test.doc -o C:\test\test.pdf

If you can run above command line in Command Line Window correctly, please call above command line from PHP by shell_exec() function or other web applications, then you will get it work properly.
