This is the first time I have used CCleaner.
It is installed to C:\Program Files\CCleaner
When I click on the desktop icon, it goes to an hourglass for a split second and then nothing. I can still use my computer, I just can't open the program.
When I click on the desktop icon multiple times quickly, I can see a window for CCleaner open for a split second, but then it closes.
I assume I installed the CCleaner v2.05.555 - Standard Build version. Is that the one that is mirrored on the main download page?
