Unable to move beyond V5.45.6611

I recently renewed my subscription after it had lapsed for a short period.

I registered and went through the procedure to register.

I am having trouble updating to the latest version (5.51.6939) because I think the program is trying to install into

Windows XP. Seems strange but I have removed every file relating to CCleaner except one file with prefix 5.51

I hope I have not confused you. Can you please help?

Further, I am using Windows 7.

Hi,

If you have a paid subscription, it would be best for you to contact Piriform directly rather than go through the community forum.
