Applies to: ZWCAD 2018, ZWCAD 2017

Issue:

After you install ZWCAD 2017, you may find that there is no view in the preview pane of Windows Explorer.


Reason:

This is because some .dll preview function in ZWCAD 2017 is not provided. We are developing it now and before it is done, you can try the following solution.

 

Solution:

  1. Download the FixPreivew

  1. Unzip the file, and then run FixPreview.exe as an administrator;

  2. If it fails, please download Dependency Walker and DirectXRepair to troubleshoot.

  1. Run depends.exe, and open the FxVistaPreview.dll to check the related .dll modules. The FxVistaPreview.dll need to be consistent with the system, in other words, you need to select the .dll in the x86 folder if you are running a 32bit system, as well as x64 for 64bit. If there is some module are label as yellow as follows, you need to go to step b.

  1. Run DirectX Repair.exe if in Win7, or DirectX_Repair_win8_win10 in Win8 or Win10. And then click the button at the upper right corner. The program will run automatically to repair the .dll modules.

  2. After done, you can go to (1) again. This time, it should be working. 

Additional Information:

You can also manually edit the Registry to complete the step (1):

  1. Download the FxVistaPreview.dll and copy it in the path

C:\Program Files\Common Files\ZWSoft Shared or C:\Program Files\Common Files (x86) \ZWSoft Shared,  Run CMD as Administrator, and run regsvr32 "C:\Program Files\Common Files\ZWSoft Shared\FxVistaPreview.dll"or run regsvr32 "C:\Program Files (x86)\Common Files\ ZWSoft Shared\FxVistaPreview.dll"

  1. Run Regedit in Run to open Registry Editor, locate to Computer\HKEY_CLASSES_ROOT\.dwg, as the following picture shows, you can see ZWCAD.Drawing.2017 (this step is not important)

  1. Locate to Computer\HKEY_CLASSES_ROOT\.dwg\shellex

If there is no "shellex" as the above picture shows, then create one named "shellex". And then create a new key named {8895b1c6-b41f-4c1c-a562-0d564250836f} if there is no such key, and right click on the new key to create a new string value and set the value data to {6AD4617F-D034-4d66-AE9E-143247611403}.



That’s all!
