Acro. Pro. Std. Upd. T1. T2incr. msp This is the Acrobat 9 pro standard version See Screenshot i highlighted both as i own both versions Someone has already posted some notes on this but i think this is the only place where you have to be very discerning and to pick the right version of update. Why do i say this Starting from 9. Acrobat. Upd. 91. From here on, there is no distinction between the Pro, Extended version or the standard version. Adobe should listen how are users to knowHow To Update Adobe Acrobat 9 ProPerhaps some notes will be helpful too. Try to do manual update up to 9. If it does not, you may have to manually go up to 9. Once there and done, you should get to 9. See Screenshot highlghted from where you should try the automatic upgrade after you get to these levels If you are trying to do it manually, the below number of manual updates look very daunting. Regards, Michael. PS. Adobe has all the resources in the world, to either write a script which should be easy enough to follow or at least some legible notes for the layman as to which files are required for which version etc life would be much simpler and enjoyable and supporters of Adobe would be more willing to have another go with new products from Adobe. Not just suck our blood and throw us under the bus and with their burn and scotch policy. The simple reason why the update files are there is prevent a public outcry because Adobe will turn around and say the files have been made available to the users and the public so stop. Just a litttle pointer and help along will go a long way. Is it so difficult to write a page or 2 of notes Adobe, go figure that out.
