I have to keep reinstalling parallel tools for coherence to work

Each time I start up my MacBook Pro I have to reinstall parallel tools in order for coherence to work. I have Mac OS 10.10 and Windows 7 and Parallels Desktop 10. Anyone know what the issue is and how to resolve?

 

Hi Dan,
Please follow the steps as given below and check how it works.
1. Shutdown the Virtual Machine ( Click on Actions -> Shutdown )
2. Uninstall Parallels Desktop 10 completely from your Mac by using pdremove.zip app as given in the article : http://kb.parallels.com/122653
Note: Your Virtual machines will not be affected by this procedure - only Parallels Desktop application will be uninstalled.
3. On your Mac, please go to Finder -> Applications -> Utilities -> Disk Utility -> Select : Macintosh HD -> Choose : Repair Disk Permission.
4. Re-boot your Mac once the repair Disk permission is completed.
5. Start the Virtual Machine.
6. Uninstall Parallels Tools and re-install it again by following the steps as given at : http://kb.parallels.com/4841
7. Restart the Virtual Machine once again.

 

Thanks for the input but I"m a little confused. I don't see in your steps where/how to reinstall Parallels 10 after I completely remove it. Can you explain or revise the steps you gave to address that?
