Installing Adobe Acrobat Pro on my new desktop

you need to clean up whatever you've already done.  ie, if you can uninstall acrobat do so.

if you have a perpetual license and windows, clean per Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs, then restart your computer and properly install using the installation files.

if you have a subscription, the process is different.

• Download and installation help for Adobe links

• Download and installation help for Prodesigntools links are listed on most linked pages.  They are critical; especially steps 1, 2 and 3.  If you click a link that does not have those steps listed, open a second window using the Lightroom 3 link to see those 'Important Instructions'.

And a big thank you to Jim @ Prodesigntools for helping me with these links!
