I am using wordpress 3.5.1 and went to tools->import-> wordpress. Its unable to download and install.
"The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature"
I have also tried to update 'wordpress importer' on another existing wordpress installation, but there also getting the same error as above.
I have tried on localhost wamp server 2.2.E - 32bit, windows 7, php 5.4.3.
Please fix the issue.
