This solution works! I have the same problem when trying to install the DLC, now issue solved! Thanks a lot! Really appreciate it!
After working really hard I finally solved this problem. I have no idea why it occurred in the first place but looks like Ubisoft games have a habit of messing up registry entries when installing. Here's what you do:

- Run Regedit

- Find the folder: HKEY_LOCAL_MACHINE\SOFTWARE\Ubisoft\Assassin's Creed 3, and make sure the path in InstallDir and the Version number are correct.

- Create a new key here called 1.01 (or your version no.) and inside that new key double click on (Default) and enter 1.01 (or your version no.) under "Value Data"

- Then go to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\ Windows\CurrentVersion\Uninstall

- Create a new key in this folder named exactly this: {9D15E813-0C26-41E7-ABC5-3EB06FF1B3CF}.

- Then inside that new key, create a new string named DisplayVersion, and set it value to the version of the game you have (1.00, 1.01, 1.02). Then launch the update file (1.01, 1.02, 1.03) and it should work.
 
I have the same problem, i just try TheKingofClubs fix but still having the same issues. Not sure what else to try and i checked it about 10 times to make sure it's right.

Question: Have you actually fixed that lag in boston yet? I'm having a simlar issue. Mine auto updates via Steam. The problem was notably improved but still existent after doubling my RAM to 8GB.
 
In regedit,my pc displaying-HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows

As thekingofclubs said -
- Run Regedit

- Find the folder: HKEY_LOCAL_MACHINE\SOFTWARE\Ubisoft\Assassin's Creed 3, and make sure the path in InstallDir and the Version number are correct.

- Create a new key here called 1.01 (or your version no.) and inside that new key double click on (Default) and enter 1.01 (or your version no.) under "Value Data"

- Then go to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\ Windows\CurrentVersion\Uninstall



But in my windows 7 pc,there is a key named 'Windows NT' in Wow6432Node\Microsoft

So it doesn't works , Please Help Me !!!

For 64-bit OS: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Ubisoft\Assassin's Creed 3

For 32-bit OS: HKEY_LOCAL_MACHINE\Software\Microsoft\ Windows\CurrentVersion\Uninstall

hi man. how did u make it work for the DLC. can u help me please? i can't seem to make it work and i'm not sure if i put it all correctly. what do i have to change in order to install the DLC because i get the same error when i try. can anyone help?
 


That was brilliant! I was having the same problem and now it finally works. I didn't find the first key where you said, though. I searched for "Ubisoft" and I found it in HKEY_LOCAL_MACHINE\Software\Wow6432Node\Ubisoft\Assassin's Creed 3. From there I followed your instructions and everything worked perfectly. Thanks!
