I see the error "Attempted to downgrade extension" when installing in Chrome - how do I fix this?
Please try the following steps to correct this error:
1. Download the LastPass .crx file from https://lastpass.com/download and unzip it into a directory
2. Go to Chrome menu > Tools > Extensions and enable Developer Mode
3. Install unpacked extension and select the folder where you unzipped the file.
