Installation Error: File size mismatch


I am trying to install Piwik but I am getting following error:

"File integrity check failed and reported some errors. This is most likely due to a partial or failed upload of some of the Piwik files. You should reupload all the Piwik files in BINARY mode and refresh this page until it shows no error.

File size mismatch: /home/XXXXXX/public_html/analytics/vendor/leafo/lessphp/ (expected length: 91826, found: 91857)"

Then I try installation with newly downloaded Piwik and I get same error.

I try Same Piwik installation on my second domain it is working good. But I want to install Piwik on my first domain. Please help me.
