error during import PDF files in MDM

HI,

when I try to import a PDF file in our MDM repository I got the following error:

"Importing [English [US]] 'test pdf.pdf'...failed.

Unable to open Adobe Acrobat.

See your administrator about installing Adobe Acrobat."

We are using MDM 7.1 SP3 installation on HP UNIX OS.

Does someone know what is it - I have Addobe Reader 9 installed on my PC (where the Data Manager is installed)?

Thanks for your help.

BR,

ILIN
