While using the professional license VS Code tools and trying to use the viz command qualifier, I found a separate modeler CLI installation. Both are named `syside.exe`, but they are not the same tool. Here are the differences:

```auto
CMD> syside --help
Usage: syside [OPTIONS] <COMMAND>

Subcommands:
  check Check SysML and KerML files for syntax and semantic errors (Modeler).
  format Format SysML files (Modeler).
  server Run Syside language server.
  rule Explain a rule or rules
  interactive Drop into an interactive shell with a loaded model
  reqif Import/export ReqIF files for SysMLv2.
  solver Compute attainable sets of expressions over a SysML v2 model.
  version Display the version of `syside`
  help Display documentation for a command

Options:
  -h, --help Print help
  -v, --version Display version

syside 0.10.3 f8ca4371147a2854109fef0ae84cfe3805bdfe3a

```

The questions are: a)Why are there two Sysides? b)Is this expected? and c) Why are the capabilities so different between them?

As you can see, I’ve found a way to use both, but this seems janky and possibly a product build issue (just guessing here, not blaming).

Hi Richard,

What you have found here is the `syside.exe` behind the Python library. Since you have both the CLI and Automator library installed, you have “two” Sysides.

On your last question about why the capabilities are different, I am afraid I cannot answer it right now and I can only tell you to keep an eye out for some exciting announcements that are going to come soon. 😉

Kind regards,  
Simonas
