I just put a "3dzStudioInstall.exe" in the 3Utilities" folder at the FTP. It is a 7-zip self installer.
When extracted it makes a folder with the installation package in it. Run "Setup.exe". It will set it up as a program, but more importantly it will install the runtime files, including the one that is missing.
Sometimes more than one is missing, but it crashes at the first so you do not know if there are others.
Do not replace your existing studio, you should still be able to use it.
