Can you post your system specs as Magi did please.
I get the following error
Critical Error
A critical error has occured in CCleaner, the application must now close.
Error Description:
The thread tried to execute an invalid instruction
CCleaner v3.09.1493
MS Windows XP Home SP3
AMD-K6 3D processor
187MB RAM
Trident Video Accelerator CyberBlade-i7
This is an older computer. The previous version of CCleaner was working great. Ever since we up dated we have been getting this error. How can I fix the new version or get the old one back.
