Used download manager to reinstall adobe acrobat 7 professional after upgrading OS to windows 7. Install ends but fails with error "Warning 20225. Adobe Acrobat 7.0.5 set up was unable to create a new item Adobe PDF Port & Printer". Adobe is installed but I can no longer print to pdf nor use Adobe directly to create pdf from file. This feature was available before this reinstallation.
How do I fix this?
