Went into Beta 21 under C:\Hitech Creations and checked all files.
Only saw 3D3X9_43.dll listed for Dx9............no 3D3COMPILER_43.dll listed for Dx11.
Ran Updater Beta 20 to Beta 21 again.....updater ran w\o a hitch.
Checked Beta 21 under C:\Hitech Creations again and still no 3D3COMPILER_43.dll shows listed for Dx11, only 3D3X9_43.dll for Dx9.
Tried executing Beta 21 Dx11 version again and got the same error message "can't start program due to 3D3COMPILER_43.dll is missing from your computer".
For some reason that I can't find this file is not installing.
So I turned Kapersky A\V off then reran Updater Beta 20 to Beta 21 again....updater ran w\o a hitch.
Again checked Beta 21 under C:\Hitech Creations and still no 3D3COMPILER_43.dll shows listed for Dx11, only 3D3X9_43.dll shows listed for Dx9.
So it appears that my A\V software isn't the issue at this time.
Waiting on directions.
