I tried to download Reader 9 and failed. I cleaned previous version and re tried. I failed again.
The findings of the failures: When I chose "run", the Explorer crushed with the download windows. Therefore, I chose "save", but during the installation process I received the following massage:
"Error 1305. Error reading from file C:\Documents and Settings\user\Local Settings\Application Data\Adobe\Reader 9.0\Setup Files\READER9\AcroRead.msi Verify that the file exists and that you can access it".
After visiting this forum I tried to download an older version, but the message is almost similar (the AcroRead.msi is missing).
