Card View installation problem on Joomla 1.7

I have just purchased Card View for Joomla 1.7 but get the following error mesages on install.
JFolder: :files: Path is not a folder. Path: W:\var\www\WMC_Test\tmp\install_4ef34b4b34abb
JFolder: :folder: Path is not a folder. Path: W:\var\www\WMC_Test\tmp\install_4ef34b4b34abb
JFolder: :files: Path is not a folder. Path: W:\var\www\WMC_Test\tmp\install_4ef34b4b34abb
JInstaller: :Install: Cannot find Joomla XML setup file

Please help.

Now resolved, problem with downloading using IE caused file corruption.
