Thanks for the cool idea Mazin! I just finished my Acrobat msi and it works like a charm. I am planning on going one step further and trying to eliminate some of the plugins that slow it down so much. I first saw the idea in an Inquirer.net article: How to use liposuction to repair Adobe Reader 6 I have deleted the extra plug-ins on plenty of computers and never missed them. Anyway, deleting the api files from the data1.cab is easy enough, and I see on the "add" column of WinInstall the list of files that will be copied. Before I try this out, is there any other advice you have?
