I cannot print anything from my PDF files with Adobe reader. On pressing the print button etc. I get "the document could not be printed" and after pressing OK I get "there were no pages selected to print" although there were! So I look at the Adobe reader programme only to find that although it is listed and shown on the desktop it has not been installed (at least not totally?) I now get error 1303 which says "The installer has insufficient privileges to access this directory C/prog/adobe/reader9.0 etc.... The installation cannot continue - log on as administrator or contact your system administrator" Any ideas how I should proceed ie, how do I log on as administrator and what do I do then? Who is my system administrator? Grateful for any assistance.
