MobiFlight Update mechanism fails

Since last release more and more people reported update problems of MobiFlight.

Once the download was complete, an error message was saying that it could not overwrite certain files.
The problem suddenly also exists for old MobiFlight versions where on my PC I definitely hadn’t experienced the problem before.
Did our PCs got faster?

Solution: We have to wait a second for the running MobiFlight version to close, and then we can extract the newly downloaded files.
