As it is past midnight here I will have a go tomorrow morning.
Have I understood your info correctly?
Run all as Admin:
1. Manually uninstall all .net manually
2. Reboot
3. Use cleanup tool
4. Reboot
5. Use installer cleanup utility msicuu2.exe and remove anything .net related
6. run .net installer
This is new territory for me, Shane, so I want to do it right.
thanks once again
