I have upgraded my reader to 9.1.3, selected my language "english", and ran the upgrade program. The update program says I need to install Adobe Reader 9.0 Language Support. When I try to do this, the error message is "Adobe Reader 9.0 Language Support failed to install". I have tried this with a very limited protection (ie virus detection) and with no protection. Same result. When I search the updates URL, there is no Adobe Reader 9.0 Language Support. I did install the Adobe Reader 9.1.3 Multiple Language Support (at least I downloaded and ran the program). Is this enough?
