Installation error occurred trying to Evernote

Hello experts,
Friends I am getting this installation error when I am trying to install Evernote in the computer. I got this same error at work too when I try for automatic update. Is this a bug? I have Evernote 4.6.4.8136 in Dell Laptop. Someone could help me to solve this error. Thanks for your help.

(.Bootstrapper.cpp:896) 0x643:Fatal error during installation.
