I tried to reinstall (repair) TaskVision : I got :
"A previous version of TaskVision Source code is installed, please uninstall the existing application before."

If I'm trying to reinstall is normal to have a previous version, so I did try to uninstall but I got :

"Exception ocurred while initializing the installation System.IO.File Not found Exception File or assembly

CustomActions.dll was not found."

In both previous messages the process went back. I need help to be able to install TaskVision Source again.

Thanks
