If none of the Captools/net browser based functions run and the browser just displays this error :

 

"Cannot create script engine: JScript. Error code: 8007007E"

 

Try this solution :

 

1.) Open command Prompt via Run|Cmd

2.) Type in regsvr32 VBScript and hit enter.

3.) Type in regsvr32 jScript and hit enter.

4.) Type in regsvr32 jScript.dll and hit enter.
