Cannot update Flash Player on OS X El Capitan

[NobleUplift]

This is similar to my last issue:

Cannot update Flash player on Mavericks or Yosemite?

I cannot update Flash Player from version 21.0.0.242 to 22.0.0.192. Eventually, I got Flash Player to update but I don't remember how I did it.

Once again I'm getting the cryptic:

It fails at 59% if that means anything.

Here is my log from ~/Library/Logs/FlashPlayerInstallManager.log:

The log is the exact same after every failed installation.

I thought I downloaded the DMG listed in the linked question but I downloaded from here:

Adobe - Install Adobe Flash Player

Install the DMG located at this location and the installation works:

Is your user ID by chance a member of the wheel group?  To find out, open Terminal, at the prompt type id then hit enter.  The output will list your userID, what group(s) it's a member of and a number of other items.  When you do this, do you see (wheel) in the output?

If it is, this is a known bug when Flash Player is installed using the online installer.  We're working on fixing the bug, however, don't yet have an estimate when it will be released.  In the interim, please use the offline installer posted at the bottom of the Installation problems | Flash Player | Mac page in the 'Still having problems' section.

Yes:

$ id

uid=502(patrickseiter) gid=20(staff) groups=20(staff),0(wheel),12(everyone),61(localaccounts),79(_appserverusr),80(admin),81(_appserveradm),98(_lpadmin),33(_appstore),100(_lpoperator),204(_developer),395(com.apple.access_ftp),398(com.apple.access_screensharing),399(com.apple.access_ssh)

I used the other URL I provided to successfully install Flash Player.

Thanks for confirming.  We hope to have this fixed soon.
