Advice needed - 1st try upgrading to 2.5 flopped

[Garyss]

I really hate to add to the clutter, but I need advice upgrading to 2.5 stable. My first attempt stalled. Presently DCS World 2.2.0 Open Alpha with F-5 and Nevada terrain are installed and working. In addition DCS World 1.5.8.12823 is also installed and tested. Both are in a main Eagle Dynamics folder, C drive.

 

After 10 hours of DL my computer was in the DIRECT X SETUP step with a

“unable to find dsetup.dll” message appeared.

 

An additional message stated:

can’t run C:\\Windows\System32\bin/DCS.exe(2) The system cannot find the file specified.

 

What am I doing wrong? Are there two different Updater programs? I think I was using 2.6.26.41.

Is this something I go to user support and create a trouble ticket. Or is that action inappropriate in this case?

Thanks for any input!!
