  1. 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.
  2. 2 Nergual, I always download Piriform's tools at http://www.piriform.com/download for personal use (at home). 2 hazelnut, hmm. There is no same on my PC. "Invalid chain" always. >( Fine... I'll try to fix this problem by myself.
  3. 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: 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.
  4. 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.
  5. 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?
