Acrobat XI Pro reinstall issues

Hello again,

It is a little difficult to recommend guidance with the way you have setup your disk drives.

It makes a little sense if this is a work computer and your were trying to accomplish a disk array to improve data backup redundancy. But since you've mentioned using windows 7,  it looks more like a classic case of an older hard drive setup in which you were running out of space and as a quick fix had to create another volume to install programs and user data there.

For future reference, specially if you are considering Windows 10, never ever install any operating system with programs and user data in a single drive.

You may however, repartition a large harddrive and assign a dedicated logical pertition in it just for user data, but if the  physical hard drive gets damaged and dies, so does all the important  user data.

If you have several disks is better to let  the C drive be the physical volume that

will have the Operating system and boot files installed in it.

Even though what you are trying to do is smart, still you should not compromise installing windows programs to a different logical partition in the same drive or separate physical drive. 

The right approach is to always plan ahead and have a large enough hard drive that you can setup for both of the OS and all of your programs  in it; and still have enough room to continue to add new programs.

Once you setup a C drive like this and configure all drivers and applications to work the way you want, then all you have to do is backup the entire disk image, so if one day it crashes replace the entire disk and burn the backup image in the new drive instead of manually trying to fix everything.

Your user data, on the other hand, should always be on a separate physical volume, for the same reasons mentioned above. If C drive goes dead you still have your D drive alive and all you have to do is backup that drive regularly.

If C drive crash but does not dies, it is easier to troublshoot C drive and reinstall the OS without messing with user settings and data files of D drive.

There are Microsoft group policy editing and upgrade deployment assessment  tools that allows you to automate this process, like for example, to save network settings, ip addressing configurations, network mapped drives, user profiles, user preferences, and such in an automated  and organnized fashion.

But going back to the main issue, I Don't think you have to figure out too much how to remove Adobe AcrobatXI registry keys manually, if what you are referring to has to do with licensing and registration.

If you achiev these guidelines successful, after you reinstall Adobe Acrobat XI you also need to update it again to its latest version to avoid additional errors with your new setup.
