I get the above message when trying to install the latest version of Malwarebytes. I've tried numerous times with the same result. I've downloaded the latest version a couple of times within the last month with the same result. I've run my Avast & Malwarebytes scans with all clear results. I have Win 8.1 on an HP Pavilion P6-2326s w/8gb of ram.
Thanks for any help offered!
