Hi Acct,
We apologize for the delay in response.
Uninstalling the application using cleaner tool should help resolving this problem. You may try once again, use the cleaner too to remove the application and its old traces - Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs
If it still doesn't help then create an hidden administrator account, following the steps mentioned below -
- Enable Built-in Administrator Account in Windows.
1- First you’ll need to open a command prompt in administrator mode by right-clicking and choosing “Run as administrator” (or use the Ctrl+Shift+Enter shortcut from the search box).
Note that this works the same in all versions of Windows. Just search for cmd and then right-click on the command prompt icon in the Start menu or Start screen.

If you are in Windows 8.x or 10 you can right-click on the Start button and choose to open a command prompt that way.

2- Now type the following command: -

3- You should see a message that the command completed successfully. Log out, and you’ll now see the Administrator account as a choice. (Note that this screenshot is from Vista, but this works on Windows 7 and Windows 8 and Windows 10)

You’ll note that there’s no password for this account, so if you want to leave it enabled you should change the password.
Disable Built-in Administrator Account
Make sure you are logged on as your regular user account, and then open an administrator mode command prompt as above. Type the following command:
net user administrator /active: no
