Missing or Invalid MSINET.OCX in EnergyPlus 9.3

I downloaded the latest version (9.3) onto my lenovo thinkpad which is running windows 10, and when I try to run EP-Launch it comes up with a message saying "Component 'MSINET.OCX' or one of its dependencies not correctly registered: a file is missing or invalid." I tried unistalling and reinstalling as well as restarting my laptop and it is still giving me the same error message.

Unmethours is software agnostic, so please do mention the software you're using explicitly, including tagging it correctly as a "EnergyPlus" question in this case. thanks!

Thank you, EPLaunch is now working properly.

This is a known bug in 9.3 that was fixed after the release, cf issue#7973

Confirm that the "missing" file is present in C:\Windows\SysWOW64

Then open a command prompt (cmd.exe) as an administrator and type the following registration command:

regsvr32 c:\windows\syswow64\<missing-file-name.extension>

In your specific case:

regsvr32 C:\Windows\SysWOW64\MSINET.OCX

Step by step instructions with images to make sure you get through it:

1.Open cmd.exe as admin:

2.Type the commands to register the DLL/OCX (the first one - dir - is optional, you can check in the File Explorer instead to ensure that the missing OCX is correctly placed atC:\Windows\SysWOW64\MSINET.OCX)
