Unable to resolve the error.Acrobat_PATH environment variable either not set or is invalid.

While using the following code

ExportPDFResult result = pdfGenClient.exportPDF2(

                inDoc,

                inputFileName,

                ConvertPDFFormatType.RTF,

                null);

I am getting the exception.

Error OCCURRED: ALC-PDG-080-023-Acrobat_PATH environment variable either not set or is invalid. Please set this variable to point to Acrobat.exe in Acrobat version 10. Acrobat_PATH should be set to

<Acrobat_Home>\Acrobat 10.0\Acrobat\Acrobat.exe. Here <Acrobat_Home> is the parent folder where the Acrobat is installed.

I have configured the Path variable as

Microsoft Windows [Version 6.1.7601]

C:\Users\pushpendra.singh>echo %Acrobat_PATH%

C:\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat\Acrobat.exe

C:\Users\pushpendra.singh>

Do i need to downgrade and install Acrobat 10.I was under the impression that back porting should always be supported by Acrobat 11.

Let me know

Regards
