If you want to see if it is there, you can run this from a command prompt (change the e: to a local drive)
reg export
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags" e:\appcomp.txt
Needs to be on 1 line. Then open the txt file and search for
BlueIris
You might need to search for Blue or Iris or Blue Iris depending on how it is stored in there. If you find it in there, you will need to do the steps in my previous post, or edit the registry.
You may have to do the same thing for
reg export
"HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" e:\layers.txt
You should have 1 entry there as below (different drive path)
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]
"E:\\Blue Iris 3\\blueiris.exe"="RUNASADMIN"
