wix boodstrapper uninstalling .net framework but it shouldn't

Question

I have a wix bootstrapper that is checking if .net framework 4.0 is installed and if it isn't it should install it. This works. but now i want to uninstall the program but it wants to uninstall the framework asswell. This should not be happening and i looked all over google but i couldn't find a solution. Iam still looking for an awnser on the net but a tip would be helpfull

I tried to just uninstall the app with add/remove program in windows but when i run the boodstrapper it wants to uninstall or wants to repair the installation. this is my code:

You need to add a Permanent attribute to ExePackage and set it to 'yes'.

This means it won't be uninstalled.
