1) Open the registry editor by selecting "Run" from the start menu and then typing in "regedit".
2) Browse through the registry and select the entry mentioned in the error message.
3) Choose "Permissions..." from either the edit menu or by right-clicking on the registry key's parent directory.
4) Click the "Advanced" button to add a new user.
5) Type in "Everyone" as the new user and click OK (it may not be necessary to give everyone full control but this is what I did and it worked).
6) Configure the permissions for user "Everyone" to "Full Control"
7) Uninstall the software (if necessary) and re-install.

USE REGISTRY TO REMOVE ITEMS FROM INSTALL/UNINSTALL LIST
How do I get rid of what seem to be eternal names in my Add/Remove Programs Properties dialog box?
There are a few ways to remove programs from the Install/Uninstall tab (the one that appears when you open the Control Panel and double-click Add/Remove Programs). First try from the Add\Remove Programs list again and see if Windows actually tells you that it will remove it from the list for you.
You can also do it using the Tweak UI PowerToy: Open the Control Panel, double-click Tweak UI, select the Add/Remove tab, select an item you'd like to remove, click the Remove button, then click Yes to confirm.
Don't have Tweak UI? You can still clean out the Install/Uninstall
list, but you'll need to do a little Registry editing. (Note: As
always, back up your Registry files--System.dat and User.dat, hidden
files on the root of your hard drive--before proceeding.)
Open the Registry Editor--select Start, Run, type
and click OK. Navigate your way to
In the left pane, with the Uninstall key expanded, right-click any
item and select Delete. Click Yes to confirm, and that item is
officially off the list. Repeat these steps for each item you'd like
to remove, then close the Registry Editor.
