Answers
What are the differences between the Lite version and the Pro version of Twebst Automation Studio?
- Some Twebst Library functions are not available in LITE edition and Web Macro Recorder produces only VBScript code. Here is the list of disabled features in Twebst Lite Edition
Do I need to install Microsoft .NET Framework to run Twebst macros?
- No, Twebst Library does NOT depend on any .NET Framework version but Twebst Web Recorder requires Microsoft .NET Framework 2.0. That means .NET Framework is only needed when creating macros and not when running them.
What are the system requirements for Twebst?
- Twebst Automation Studio was tested against Windows 7, Windows Vista, Windows XP (32 and 64 bit) with Internet Explorer 6.0, 7.0, 8.0
Is Windows 64 bit supported?
- Yes, Windows 64 bit is supported but Twebst Library can only be used from 32 bit processes and only with Internet Explorer 32 bit version. Twebst Library 64 bit will be available in a future release.
Why does my script fail to start on Windows 64 bit with error: "Automation server can't create object"?
- Twebst Library is available only for 32 bit processes; that's why .js and .vbs Twebst web macros must be run by 32 bit versions of wscript.exe / cscript.exe you may find in %windir%\SysWOW64 directory.
Can I use Twebst Library with Web Browser Control in C#/Windows Forms project?
- Yes, Twebst Library can work with web browser control by attaching to ActiveXInstance underlying IWebBrwoser2 object (see AttachToNativeBrowser library method).
I come across following error message: "Can not properly create a new browser object. It is possible that TwebstBHOPS.dll is not properly registered". What should I do?
- Reinstall the product
- Manually register TwebstLib.dll, TwebstBHO.dll and TwebstBHOPS.dll using regsvr32.exe tool (on Vista/Win7 Run as admin)
- Check if Twebst BHO extension is enabled in Internet Explorer (Tools/Manage Add-ons/Toolbars and Extensions).
- Enable third-party browser extensions in Internet Explorer (Tools/Internet Options/Advanced/Browsing/Enable third-party browser extensions).
Is it allowed to redistribute Twebst Lite Edition?
- Yes, you are allowed to redistribute Twebst Lite Edition under Redistributable License Agreement conditions.
Is it allowed to redistribute Twebst Pro Edition?
