App Installer Says MY Windows Version is unsupported

As I asked have you extracted the files from the zipped log collector because if you do NOT and try to run on the zipped log collector you get that error

Save log collector V2 log collector 1.1x.zip to where (downloads for example) you want.
Right click on V2 log collector 1.1x.zip in the Downloads folder and select Extract all. This will create a V2 log collector 1.1x folder.
Open the V2 log collector 1.1x folder and double click on the log-collector shortcut.

So I presume you were not actually executing the procedure as shown.
Whatever the reason, I wish you good luck in getting this problem sorted.
I cannot assist you further without the full logs. There is NO personal information collected by the log-collector, that can be used for malicious or improper purposes.

I would point out to you that 1000`s of users of this site and indeed others have used that log collector and please be assured that IF personalized data was collected, this site would have numerous posts to such effect

MS reported this week that there is problems with some apps due to an update and they are working on a fix which should beout soon so keep checking for updates
