Q
What does error 155 stand for ?  
 

Error 155

Means some change in windows file.

The solution to this is to reinstall CARApro software without deleting or removing previous version of CARApro. Just reinstall software. After 99% of installation is over, it will prompt you an error message “could not transfer cara copy protection” Click ok and go ahead with completion of installation.

This should solve the problem. Or else contact us at drpravin@vsnl.com
