FSS E-Jet Updatre to v.0.9.9 worked only on one PC and then nowhere else

[Matschtaucher]

What is this?
Today the experimental release to version 0.9.9 is scheduled (no time given...)

I have a couple of PCs with MS Flightsimulator. Most of them have the version 0.9.8 installed.
I started the first one and could update to v 0.9.9. Ok.

The I started the 2nd PC and aerosoft One stated: There is no update. You have the latest version.
I re-started Aerosoft One, but no luck.
Then I uninstalled  FSS E-Jets, 
By choosing "experimental branch" at the new installation I got the version 0.9.8-rev2.
There is no way to get 0.9.9.

Got back to PC Nr. 1 and checked  Aerosoft One.
It states, that I have v 0.9.9 installed but I could UPDATE to version 0.9.8-rev2

What the heck???
