Cannot install - Installer error: RegSetValueEx failed error code 5

I get the following error message at the end of the installation procedure:

Something is wrong because if i create a key manually in the uninstall registry, i get no error, which means i have access rights to this place.

So what is your operating system?.

Looks like a Vista or Win7 window... Try running the installer by right-clicking and choosing "Run as Administrator." That usually get you past permissions glitches. Most likely to happen if you're running in a non-administrator user profile. The specific error is popping up when the uninstaller reference is being written to the registry at the global machine level (uninstaller is being registered for any user account on the computer).

All the latest versions of Windows still use the same Registry, its 64-bit versions having added their WOW keys,
