Additional Information

Acrobat trial and Adobe Reader use NetOpsystems Nosso optimizer to ensure the download files are not corrupted. This utility extracts the contents to the user temporary folder. Microsoft Windows Vista, with User Account Control disabled, does not allow write and execute access to the %TEMP% folder.
