fix repair see issue #8
start renaming custom actions to avoid confusion
Create custom actions for setting the HKCU component of active set up see issue #7. Custom actions are wrapped (to avoid logging logic duplication)
Custom action create HKCU key in HKCU 64 registry. Try to force 32bit registry (Wow6432)
Systematic use of the 32 registry does not work because for HKCU .NET apis does not know the Wow6432 that are used only by active setup.

Therefore ask .NET apis if OS is 32 or 64
