Opening Ccleaner causes computer reboot

Anyone have this problem? Each and every time I open Ccleaner, the computer reboots. Can't get it to open. Have removed the program and then re-installed. Any other suggestions?

More info is needed, such as what:

* Windows OS version (Win 7, Win 8.1).

* CCleaner version.

* Antivirus software you have installed.

Each and every time I open Ccleaner, the computer reboots. Can't get it to open. Have removed the program and then re-installed. My cumputer have new format , just today I format this machine, in fact I have format another computer and cclenaer reboot the other computer.

I think that is not the machines

Each and every time I open Ccleaner, the computer reboots.

See post #2. Give info if you want valid help.

Also sending the same thing to me in a PM is against forum rule 15, help is to only be given in the open forum where everyone can benefit.

Whether or not it is the machines, both posters MUST provide the information that @Andavari requested.

I'm wondering, perhaps, are you running ccleaner on windows XP with only Service Pack 2 and not SP3. But without knowing from both of you there's no way to provide aid, and, more importantly, there's no way to know if you both are experiencing the same "bug" (or a bug at all)

I was thinking the WinXP SP2 bug as well. Might as well link to it, it's here:
