its now clear its removing the previous version is the issue, so when i go to control panel and uninstall programm and when i uninstall paint.net i get the following:
there was a problem with this windows installer package.
a program required for this install to complete could not be run.
and when i opt for "repair":
the feature you are trying to use is on a network resource that is unavailable
click ok to try again, or enter an alternative path to a folder containing the installation package paint dot net_835170366.msi
thanks please continue to help
