maxwell999 Posted April 26, 2018 Share Posted April 26, 2018 Actually I went back to version 5.40. It's much faster and it has the old presentation of results. 5.41 and 5.42 suck. Link to comment Share on other sites More sharing options...
quicktrick Posted April 27, 2018 Share Posted April 27, 2018 The same issue again. Chrome profile deleted. After unchecking 'Applications -> Google Chrome -> Internet History' everything is OK. Windows 10 (1709 build 16299.371) Chrome Version 65.0.3325.181 (Official Build) (64-bit) CCleaner v5.42.6495 (64-bit) Link to comment Share on other sites More sharing options...
johnny boj Posted April 28, 2018 Share Posted April 28, 2018 I can confirm that the latest (free) version of Ccleaner v5.42 wiped out my Chrome (latest) settings. Has not happened ever before, only with the latest release 5.42. Happened on two of my machines, both running Win7 (with all the latest updates), one is 64-bit, the other 32-bit. Ccleaner v5.42 has a nasty bug about the Chrome settings. Please overview and correct the issue. Thanks PS: just overinstalled v5.41 over the v5.42 and the issue is not there with 5.41.

Guest Stephen CCleaner Posted May 1, 2018 Share Posted May 1, 2018 Quick update: We believe we know the cause of this issue and are working on a fix. We will release this as a hotfix as soon as ready. It doesn't look like it affects all users of Chrome, it seems dependent on certain data existing in the profile, which explains why it wasn't caught in testing. Nonetheless we will look at our 'regression pack' (the battery of tests we perform on CCleaner before releasing it to the wild) to see if there is a way to catch this kind of issue in the future.

jengr2015 Posted May 5, 2018 Share Posted May 5, 2018 I am not sure what to do at this point in time. I am using windows 8.1 and the newest version of ccleaner. I check my mail in chrome and then I log out and then I use ccleaner and then I shut down. The next day I do the same thing again with no error messages. Is it safe for my computer to continue to do this? It won`t cause any damage will it? Link to comment Share on other sites More sharing options...

Guest Stephen CCleaner Posted May 11, 2018 Share Posted May 11, 2018 Hi everyone, We have a fix that has passed testing for this and we plan to roll it into v5.43, which is currently scheduled for Thursday 17th May. We have collaborated on the fix with the Yandex browser team, who were able to provide some specific conditions for reproducing it. A (Technical) Explanation of the Issue There were actually two issues at play here: #1 - JSON 'double' format Some of Chrome's data is stored in condensed JSON format. If we want to clean one thing but not another, we need to open the file into a workable JSON format, clean out one or more specific sets of data and then convert the file back to the original format. A JSON wrapper function written a long time ago was converting long 'double' data types using the scientific -or exponential- double format. That's fine for internal CCleaner use, because exponential doubles use less space than float doubles. But the Chrome (and Chromium) profiles expect these values to always be in a float double format, and Chrome would crash if it encountered an exponential double. The fix is that this wrapper now always converts to float format when used for browser cleaning. #2 - Comma decimal separator In some countries (such as Russia) it is usual to use a comma as the separator in a decimal value, e.g. "4987434,3263543746". Yandex highlighted that running CCleaner on a Windows environment set to use such a preference would result in changes to float values. E.g. "2487.0982" would become "2487,0982". This would cause the JSON data file to be saved incorrectly. Why did it happen now? We're not entirely sure why this only just started happening or why it only happens in some cases. It seems that Chrome made some changes in how it stores certain values and now uses very long floats for this. This exposed some incompatibilities in CCleaner JSON handler code that wasn't originally written for handling the Chrome profile specifically. However, it's also true that not all profiles seem to contain these long doubles; internally we were unable to reproduce the problems people were having because our profiles (even those with lots of use) did not contain the double values triggering the issue. What are we doing to avoid this kind of thing in the future? We have discussed this internally. The CCleaner code has been written over many years and does not utilise more modern trends in software development such as code unit tests. The team would like to add unit tests, starting with the most utilised parts of the code and especially code which is used in conjunction with other software that can change without our knowledge or control (e.g. browser cleaning, system cleaning & application cleaning). This will be a long process to build up these tests, but we believe it has strong value in reducing the risk of issues like this from arising in the future, and is ultimately worth the effort.

TheOwner Posted May 11, 2018 Share Posted May 11, 2018 After Chrome update to version 66.0.3359.170 I cannot use CCleaner anymore. Previous version of chrome can be damaged by CCleaner but there were workaround (clean temp files by chrome first, then run CCleaner = all ok). But now if I clean by Chrome self first, then run CCleaner = all settings wiped after each run of CCleaner. It is worse and worse, so i had to uncheck all chrome options in CCleaner.
