[SOLVED] MALWAREBYTES does not install nor dl!! Help

I hadn't been able to update virus definitions for a long time. Contacted MWB and they said to do a complete uninstall and clean install but my computer won't allow that. I have gotten, "Source code error, cannot read" and 'root file not found '. Told MWB about this, told me to dl and install clean repair kit but again my computer says I can't.

I am not computer savvy so I do not know what is going on. Right now I have completely removes all traces of MWB from my computer using the removal tool from them.

My husband's laptop an Acer running W8.1 is having the same trouble removed it from there too.

Can anyone tell me anything about all this? thank you:ermm:
