Hi and thank you for your post.
This does not happen on all computers so is not easy for us to recreate, the more information you can provide the more it will help us resolve the issue sooner. If you could try the following:
1) Download the latest software and extract it into a separate folder
2) GO into command prompt by pressing the Start Key then click on Run, type in CMD then press enter
3)Go to the directory where you extracted the download and type in the following:
setup.exe /v"/Lv picofull.log"
4) This should run your installation wizard and it will log information in a log file. When the roll back happens and the software exits, attach the picofull.log file in the forum as post.
