Yes, I downloaded the CCleaner Portable zip file onto a USB stick and unzipped it there. Again, I get the same error conditions. I have previously tried both the normal and slim versions without success as well.

So running v5.0 from a USB still results in the same error conditions.

Scheduled the check for disk errors on reboot. installed versions past 4.10 and they all failed, same as before. Still only v4.10 is the last one that works. Could CCleaner require services that may not be running on my laptop? Does it require the presence of any DLLs? Again, I appreciate any help.

Now this is peculiar. I completely uninstalled CCleaner and the reinstalled it with the colour scheme set to Vista Basic. After this reinstallation, CCleaner still failed; but the colour scheme message did not occur. So I set the colour scheme back to Aero and still not colour scheme message. No program shows up in Task Manager with PID 6072; yet CCleaner still fails. I did verify that the theme service is running as well. As Kroozer suggested, I ran the SFC utility as well. It claims to have corrected some files; but CCleaner still fails to work, even after a reboot and reinstall. I am still only able to run v4.10 successfully.

The colour scheme is the regular old Vista one. When CCleaner starts up, a pop-up message says The color scheme has been changed The following program has performed an action that requires Windows to termprarily change the color scheme to Windows Vista Basic. Program: <Unavailable> Publisher: <Unavailable> Process Identifier (PID): 6072 Windows will automatically changes the color scheme back to Windows Vista Aero when this program or other programs performing similar actions are no longer running. It seems to only affect the CCleaner window. After I clear this message, it all reverts back to normal. So I tried setting my colour scheme to Vista Basic since it is not important to me. Now I do not get this message about the colour scheme; but CCleaner still stops working with the first message that I have identified in this thread.

I have tried completely removing each version and reinstalling. Nothing changes.That is why I am expecting the CCleaner requires the presence of some DLLs or other system files that could possibly be missing from my laptop. I do not have any issues running it on other machines.

The utility starts and changes my colour scheme back to basic. Then this message appears. CCleaner has stopped working A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is Available.

The last functioning version of CCleaner on my HP Pavilion laptop is 4.10. All subsequent releases (up to 5.00) fail to run. They download; but as soon as it tries to start, I get a Windows error. Can anyone assist? I have Vista, service pack 2, 1.9GHz processor with 3G RAM and loads of free hard drive space. Perhaps CCleaner requires 1 or more DLLs that could possibly be missing from my laptop? Any assistance would be appreciated.
