You may receive the "Invalid command line" error message when you run the Access Conversion Scanning Tool at the command prompt

When you try to run the Access Conversion Scanning Tool, also known as Adscanner.exe, at the command prompt, you may receive the following error message:Note The Access Conversion Scanning Tool is included with the Microsoft Office Access 2003 Conversion Toolkit.

This problem occurs if the syntax of the command that you use to run the Adscanner.exe program is not correct. The following list describes the three main causes of this problem:

• At the command prompt, you set the value of a command-line argument to an unsupported setting in the syntax of the command that you use to run the Adscanner.exe program. The following example shows an unsupported setting for the value of a command-line argument:

  ADScanner <ResultPath> /acc:off

  The only supported setting for the /acc command-line argument is on. Instead of specifying off to prevent the scanning tool from collecting the Access properties, you do not use /acc at the command-line.
• At the command prompt, you specified a command-line argument more than one time in the syntax of the command that you use to run the Adscanner.exe program. The following example shows a command-line argument that is specified more than one time:

  ADScanner <ResultPath> /acc:on /acc:on

  In the previous command-line argument, you specified the /acc command-line argument two times in the syntax of the command. Therefore, you receive the error message that is mentioned in the "Symptoms" section.
• At the command prompt, you specified a command-line argument that is not valid in the syntax of the command that you use to run the Adscanner.exe program. The following example shows a command-line argument that is not valid in the syntax of the command:

  ADScanner <ResultPath> /access:on

  In the previous command-line argument, you specified the /access command-line argument that is not valid in the syntax of the command. Therefore, you receive the error message that is mentioned in the "Symptoms" section.
  
  Note The <ResultPath> placeholder is the placeholder for the full path of the folder that stores the results of the scans.

To resolve this problem, you must make sure that the command-line arguments are valid when you run the Adscanner.exe program at the command prompt. Before you run the Adscanner.exe program, verify that the syntax of the command that you use to run the Adscanner.exe program is correct. To verify the syntax of the command, do the following:

• Make sure that you have not specified the command-line argument explicitly if you want to use the default setting for a command-line argument.
• Make sure that you have not duplicated any command-line arguments.
• Make sure that you have not used any arguments that are not valid.

This behavior is by design.
