After I replaced WIN XP with WIN 7 many attachments won't open. Message says Adobe Reader (using Adobe X) can't open "xxxxxxxxx.pps" because it is either not a supported file type or because the file has been damaged (for example, it was sent as an e-mail attachment and wasn't correctly decoded) This never happened with WIN XP. Any suggestions nykirk
How are you trying to open them?
I ask because a .pps is a Powerpoint slide show and Adobe REader only opens PDF's.
So, are you double clicking on a file and REader is trying to open them or are you opening Reader then using File>Open and navigating to the file or something else. As many details as you can supply would be good.
