Hello,
I found it with a web search, even gave directions to install it.
If this still doesn't work please try these steps.
1. Open a DOS PROMPT (or run "command").
2. Enter the command cd \windows\system" and press enter .
3. Enter the command regsvr32 c:\windows\system\msstdfmt.dll and press enter .
I needed it for a new VR bot I downloaded.
Thank you for trying to help.
Hugsss
