linkz Posted May 25, 2012 Share Posted May 25, 2012 Good day! I have a problem. Two days ago I reinstalled operation system (Windows XP SP3 if it matters). All system patches was installed too. So, when I trying to verify digital signature of CCleaner.exe with Sysinternals SigCheck tool then I got "Invalid chain" message. Same result I've got in explorer on digital tab. Is it truth that Piriform's tools hasn't correct digital signatures? I personally doubt because on XP SP2 and Win7 SP1 under VMWare this feature is lost. How to fix this problem if it possible?

linkz Posted May 27, 2012 Author Share Posted May 27, 2012 I understand the problem is not solved due to the fact that no one get same bug. I was planning to buy a license to deploy CCleaner in my office, but if CCleaner hasn't the correct certificate then no point to buying it. I was sent here with Piriform's support service, but here again there was no reply. The impression that Piriform absolutely indifferent to my problem as other forum's guys. May indeed certificated that have Piriform's tools are not valid. It seems like truth. Link to comment Share on other sites More sharing options...
Alan_B Posted May 27, 2012 Share Posted May 27, 2012 You seem terribly impatient for an answer to a problem that is undefined. I see no problem. This is what sigcheck told me.

linkz Posted May 27, 2012 Author Share Posted May 27, 2012 Not sure. Take a look at this: E:\BIN>sigcheck -q -a -i ccleaner.exe E:\BIN\CCleaner.exe: Verified: Invalid Chain Signing date: 15:15 23.05.2012 Publisher: Piriform Ltd Description: CCleaner Product: CCleaner Version: 3, 19, 0, 1721 File version: 3, 19, 0, 1721 Strong Name: Unsigned Original Name: ccleaner.exe Internal Name: ccleaner Copyright: Copyright й 2005-2012 Piriform Ltd Comments: CCleaner And (for example): E:\BIN>sigcheck -q -a -i F:\Installer\VirtualBox-4.1.16-78094-Win.exe F:\Installer\VirtualBox-4.1.16-78094-Win.exe: Verified: Signed Catalog: F:\Installer\VirtualBox-4.1.16-78094-Win.exe Signers: Oracle Corporation VeriSign Class 3 Code Signing 2010 CA VeriSign Class 3 Public Primary Certification Authority - G5 Class 3 Public Primary Certification Authority Signing date: 16:15 22.05.2012 Publisher: Oracle Corporation Description: VirtualBox Product: Oracle VM VirtualBox Version: 4.1.16.r78094 File version: 4.1.16.78094 Strong Name: Unsigned Original Name: VirtualBox.exe Internal Name: VirtualBox Copyright: Copyright © 2009-2012 Oracle Corporation Comments: n/a Ahh? VirtualBox certificate is signed Verisign too, effect is different. Why? It's not a bug of SigCheck. I wrote a small application on C but took the same result.

Moderators Nergal Posted May 27, 2012 Moderators Share Posted May 27, 2012 did you download ccleaner from piriform or file hippo? or from somewhere else? As @Alan_B suggested have you made sure root certificates has been updated in windows? it's an optional update. ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF. Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark) ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.

Moderators hazelnut Posted May 28, 2012 Moderators Share Posted May 28, 2012 Have you gone to Windows Updates and looked at the optional updates available for your machine? As has been pointed out your machines root certificates may be out of date. Or better still read here for some background info, the April Root Updates for XP users are available on this page. http://support.microsoft.com/kb/931125 Root updates for Vista and Windows 7 are done differently than XP as readers will see from this page.

linkz Posted May 30, 2012 Author Share Posted May 30, 2012 2 hazelnut: Neah! But I fixed this bug with Sysinternals Process Monitor (great tool at last!). Now I see that CCleaner.exe is digitaly signed. Thanks a lot to all. Link to comment Share on other sites More sharing options...
