CCleaner Digital Signature? (Off Topic) [Resolved]
« on: September 21, 2017, 04:12:51 PM »
Is anyone else having issues when installing CCleaner due to the new digital signature?

When the install gets to a certain stage I get a screen giving the three options...abort, retry, or ignore.  ???

Who issued the certificate ?
Can't check myself a.t.m. as I only have a old tablet.

Sounds like there was a little problem with Windows adding/accepting in the trusted certificate list.

The new CCleaner 5.35 install file is signed with a Symantec certificate originated 09/19/2017 and good until 10/11/2018.  The previous installer also had a Symantec certificate that was issued a couple of years ago.
