Build 5.38 upgrade from Piriform fails to install on Win 7 Home. Earlier versions - no problem! Multiple downloads run, show cCleaner 5.38 install path, runs after "install" disappears when initial run is closed..
do you get an error message?
had the previous installed version had a custom file locating or was it a portable build?
try this...
uninstall your current version first.
then go into the Program Files folder for CC and delete its contents
(keep the .ini file if you have customised settings)
download the latest build from here; <a href="https://www.piriform.com/ccleaner/builds" rel="external nofollow">https://www.piriform.com/ccleaner/builds</a>
reboot the PC then install CC from your downloaded file.
if no luck, try the install with the PC in Safe Mode.
and try the Slim or Portable builds to see if they work.</p>
