I have been unable to install the new version of Evernote to my desktop (to my knowledge I didn't have an old version) - I have repeatedly tried to install it and immediately get the message that the installation ended prematurely because of an error and to try again. Happens over and over. On two occasions I also got this error message .\Bootstrapper.cpp:886) 0x643:Fatal error during installation. I have Windows 7 home premium. Can anyone help?
