How to Fix Error 1606 While Installing Adobe Acrobat

error 1606

I was struggling with this issue for quite some time and could not seem to resolve it. I was trying to install Adobe Acrobat Version 6 on my laptop and every time I attempted to install it I received the "Error 1606.Could not access network location…" First off I was not installing over the network, so the first thing that came to mind was a faulty disc. I contacted Adobe support and they sent me over to the Microsoft site stating it was an OS problem. After hours of trying the different "fixes" available I was ready to give up when I found a post by a frustrated Acrobat user in the Adobe forums. I tried his recommendation and it worked! I have posted this quick little guide that will help you bypass all of the supposed "fixes" online and lead you to the one that works.

Why this occurs…It turns out that when you uninstall/upgrade Office to a newer edition it keeps registry keys for those uninstalled/previous editions, during installation Adobe Acrobat for whatever reason checks these and somehow it generates this error. When you delete these unused registry keys you will be able to install Acrobat.

If you encounter the above error while installing Adobe Acrobat please follow the instructions directly below.

***Please note that this error can occur with other program installations, if this is your case scroll to the bottom of the page and try the Microsoft Fix first.***
