Impossible to edit to PAINT X6

Hello Company 

Can someone explain to me why I can not edit the bitmaps to PAINT X6 automatically 

This worked very well for 2 years! 

My last point, I re-installed in parallel CD X3 to receive a link with 32-bit Office programs 

For information, the link is not done either with X3 

Thank you for your precious help
