CCleaner find a new version of application but it is already installed same version
Oracle VM VirtualBox - Version 6.1.28 r147628 (Qt5.6.2) and application confirms this is latest version.
If one looks very closely at the listing, it shows (at least in my testing), that the New Version is "6.1.28.147628.0" and that the current version is "6.1.28.47628.0".
As such, that'd look like a mismatch to the software, and that this version is newer. Probably just a simple typo, thanks for pointing it out, we'll look into this further! In the mean time, simply uncheck the VirtualBox item when running the Software Updater.
Currently, Oracle VirtualBox is 6.1.30r148432 but CCleaner thinks it should be 6.1.30.14832 and reports the current version is 6.1.30.48432.0 even though it isn't. The version format is tricky. I just ignore the error for now.
