On installing the lastest beta's

After I’ve finished the last few beta installations I get this box below.
It doesn’t seem to affect the running of the program as far as I can tell.
But could it cause a problem later on?

This error shows that file mapping of the scrivx file extension with the Scrivener application failed. This is written within the registry, so you might try installing Scrivener with Admin rights next time.

Thanks for that tiho_d. I’ll try that next time.
