Hi, quite a newbie to this community, found it googling for the following: Recently had to uninstall and reinstall Adobe Acrobat V 7.0 as I couldn´t confirm the activation after some hardware change. However now, after the reinstallation I can´t upgrade to 7.0.7 as it used to be before, I´m always given an error message from Windows Installer like " Patch cannot be installed because the program you want to uprade doesn´t exist or it is the wrong version to be upgraded". After some research found that I could upgrade in steps from 7.0 via 7.0.1, 7.0.2 to 7.0.3, but the next step to 7.0.5 again failed. Read something about silent installs, is this a solution? A brief hint in my situation what to do? (Of course tried again un-/reinstall with cleaning tools, as usually didn´t help)
