But, before you go ahead and touch anything on the Registry app, make sure you've backed up everything. You can paste this into a batch file and run it as administrator or just open an administrator command prompt and paste it into there to quickly get rid of the entry. If disabling the Logitech Download Assistant does not resolve the LogiLDA.dll error, this calls for a slight tweak in your Windows Registry. It's almost as if someone at MS had LDA installed and didn't bother to clean up the registry before publishing the update. I tried it already and nothing seems to be messed up with the file missing.
Ok, from what I've seen you can just remove the registry entry for the dll.
