my Adobe reader has disappeared from my computer, so i'm trying dowloade it agian, but i keeps on saying that there is a newer version in msi "installation file" so it won't complete det installation...

mit Adobe reader er forsvundet fra min computer, så jeg forsøger at hente det igen, men hver gang jeg er i gang med at downloade, så siger den at der er en nyere version i installationsmappen...
