If your installer for DXGL freezes, please send me a copy of your HKEY_CURRENT_USER\Software\DXGL registry key.
To do so, do the following:
Open Registry Editor (regedit.exe).
Navigate to HKEY_CURRENT_USER then Software then DXGL.
Go to File->Export, make sure Selected branch is selected and it reads HKEY_CURRENT_USER\Software\DXGL and save the file.
Go to https://dxgl.org/contact/ and write a message, and attach the .reg file you saved using the Choose File button. Send the message with the attachment and I should receive it in my email. Simply attach the .reg file, you don't need to zip it or anything.
