I can't uninstall or delete the Reader 8 installer package (.msi) file after installing Reader 9.3.1 on my VISTA machine. I don't know why it wasn't uninstalled as part of the upgrade to 9.3 from 8.xx but nevertheless my computer denies my attempts to delete the file. It appears that everything but this large file in the Reader 8 folders are gone. Any suggestions on what tricks are required to manually dele this file and the Reader 8 folders?
You can run the Microsoft Installer Cleanup tool, but you will have to re-install Reader 9.
I installed the cleanup utility but it can't see the Reader 8 file as an installed program and doesn't present the option to remove it. I have tried to find Reader 8 so that I might reinstall the entire program and try another uninstall to see if that does the trick but it does not appear that the old program is available on the Adobe site. I'll try to uninstall Reader 9 and see if that frees up or deletes the old 8 files and then reinstall 9.
