I just bought VWD and the bridge for Carrara. Did the installation as described.Downloaded Phyton 2,7 as Philemo describes and installed it. All on Windows 10 64bit OpenGL rendering context information:

    Thread ID 8588  1454     (i)  Renderer     : GeForce GTX 970/PCIe/SSE2
    Thread ID 8588  1454     (i)  Vendor       : NVIDIA Corporation
    Thread ID 8588  1454     (i)  Version      : 4.5.0 NVIDIA 384.94
    Thread ID 8588  1454     (i)  GLSL version : 4.50 NVIDIA

But when I try to open VWD in Carrara it will open the pop-up window and ask for the path to VWD and after that..... nothing.

Paths are :
c:vwd
c:python27
c:3d programmerdaz 3dcarrara8.5

When starting VWD only from c:vwdVWDClothAndHair.exe, it starts, and I get the VWD window, but no bridge. I have even tried to run Carrara as an administrator, but with no luck. And I dont have Poser, but as a Carrara user I "have " to have DazStudio

Anyone,anywhere have any idea

Hi Varsel, In the Daz Tmp directory, you should find some debug files. They are reset every time Carrara starts. So, if you could make a try, exit Carrara and then look, you should find a file carraravwddebug.txt. if you could Pm me this file, it may help me to pinpoint the problem. Most of the time, the issue is with python.

Hi Philemot.

I assume you mean the directory we should clean now and then,and especially after a Carrara crash. It is clean. Only one file (*.combo) after starting Carrara. Importing a V4 and some cloth and trying to start VWD.

Exiting Carrara and a clean Daz Tmp directory.

I did search for the file but all my searches came up empty.

The only file I could find that reassembles anything is VWDClothAndHair.log in the VWD directory.

I'm surprised. If you have the VWD location popup, then you should have a trace file. Mine is situated in C:\Users\Philippe\Documents\DAZ 3D\DazTmp. The name of the file is CarraraVWDDebug.txt. Maybe you could make a search with that name. There may be two other files : PythonOutput.txt and PythonError.txt, but they will be empty unless python works properly.

To check another point, could you go to the c:\python27 directory and launch python.exe. You should have a cmd like window appearing. The first 2 lines in that window should be:

Python 2.7.10 (default, May 23 2015, 09:44:00) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

Can you confirm that?

Another issue could be your antivirus preventing the launch of VWDClotAndHair.exe (mine is periodically sending a popup to confirm it's safe to launch from another application). The debug file should tell us if you can find it.

Ok here we go :

No trace files, anywhere.... There is a python_err.txt and pytho_out.txt, but that those are situated in MakeHuman.

When I am running python.exe I get the same result as you.

I am running Avast as antivirus and it is usually very good to give popups, and asking for running in sandbox. But non this time. And I can run VWDClothAndHair.exe from outside Carrara.

I have also reinstalled Carrara, from DIM. And reinstalled Phyton.

I must say I'm at a loss there.

There is a 95% chance the cause lays with python, but it's difficult to prove or disprove it without trace files. If you don't mind, could you try installing PyCarrara from Frédéric Ribles and run one of the examples. It may help with checking install. Link to PyCarrara

When trying to open PyCarrara_Demo1.car I get a Error Window stating : PyCarrara.mcx failed to load.

Pressing ok, and the scene opens. Looks like all the objects are there. Playing music, but no movement ...

I have also tried to reinstall Carrara.

Using DIM - Uninstall - This doesn't remove the folders, presets,scenes and plugins etc. so I did delete the extension folder so I removed all other plugins (just in case)

Using DIM - Install

Installed VWD and PyCarrara .... And still no luck. Same errors, and no log-files.

So, it seems to confirm that Python is the cause. PyCarrara is statically linked to Python where the Carrara bridge is dynamically linked. Therefore, PyCarrara fails directly (when loading) where the bridge does so only when Python is needed.

Python path (c:\python27) needs to be in the system path. If the path stated in a previous post is the system path , then this isn’t the issue. Otherwise, the easiest way to check (I’m sure you know it, but this is a public post) is to open a “cmd” window and type the command “set path” then pressing “enter”. A list of directories separated by a “;” will then appear. C:\python27 should appear in that list

Yep... its there

Just a thought. Can there be anything with read/write privileges ...

An alternative way of checking and correcting if necessary

Could be (as always), although I can't figure out what would affect both PyCarrara and the bridge.

Could you check this entry in the registry? \SOFTWARE\Python\PythonCore\version\PythonPath under both the HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE hives.

If I believe this link (not the right version, but who knows), this is where embedded application Python call resolve the path.

It's missing from HKEY_CURRENT_USER

But I'll have to say... We are now starting to go behind my expertise in Computers. Registry editing is something that I have never done before.

Sorry about that. Python installer should have done it. Which reminds me. During Python installation, there should be a check box with something like "add python to path". It may be unchecked by default. Maybe re-installing python and making sure it's checked should solve the issue in a simpler way.

Your right about the check box, or rather there isn't any, but it is a choice of components to install. So I chose to install all.

I am starting to wonder if a total re installation of everything - including Windows is the way to go.....

Well a good excuse to go shopping..... Need an external harddrive for backup, and some usb-flashdrives for windows.....

I hope it won't come to that.

Win10 reinstalled , Carrara reinstalled, Got the carraravwddebug.txt file and sendt by sitemail.....

Will the current version of VWD (with the DAZ Studio bridge) work in DAZ Studio 4.8?
I don't expect support of an older version of DAZ Studio which is now at 4.9, but if it does work that would be helpful for me to know. Thanks!

It starts with version 4.8.0.59
