Every time I try to install Acrobat Reader 8.1.2 I am ,at a point in time during the installation process, requested to find the "Adobe Acrobat 7.0.1 and Reader 7.0.1 Update.msi" file. I do not know wher to find them (a search on my computer has not found them !). What to do and how to overcome this difficulty ? Thanks for any help !
