hey guys I went to reinstall ccleaner for the first time and all it does is open a text document cant get the installer to install ccleaner on my windows 10 machine had it installed went to update it couldnt update it what the heck is wrong am i missing something

How did you try to update?

What number build of CCleaner are you updating from?

ive used the latest update and ive uninstalled the app all together and cant reinstall the app all it does is try to open a text document when i go to download the app any ideas on how to reinstall the app thru file hippo which ive used in the past to download the builds

the 5.3old version ive already uninstalled the program but when i go to reinstall it it opens as a text document tried everything i could but i ran cleaner w/the old windows deletion checked did i screw it up
