Automation PlugIn: Can't execute JavaScript files (Beta 4)

[Eric]

"Run Focused Scripts" isn't enabled for JavaScript files, VBS yes.
Does he only use the default engine?
Or how can I execute JScript files?

Thanks

You can rename *.JScript to *.js

[Eric]

They are already named .js
I'm trying to run those in the installation dir:

Convert Images.js
Count Lines.js
Launch Elevated Command Prompt.vbs
Make Link.js
Make List (JScript).js
Make List (VBScript).vbs
Unpack Multiple Archives.js

Seems like your Windows *.js association is broken. Try to run
regsvr32 jscript.dll
command from UAC-elevated CMD prompt or Salamander, it should repair required registry entries.

I've had this issue for a long time and this command fixed it, thank you.

I suspect it's caused by installing Visual Studio or something, because I got the same problem on Windows 8.1 after re-installing the system and installing Visual Studio, Office and few other programs.
