File properties cannot be set anymore?

Question

Hi,
I have an application reading custom file properties (name/values accessible using dsofile.dll) to take actions on the processing of these files.
Using win xp/vista, right-click on file, there is a tab "custom" where file properties/values can be added.
In win 8.1 pro: no file properties available, and no way to add them! If I go to work, I can add properties, but these are NOT accessible using dsofile.dll.
If I take a file from old computer, copy it to new one, there is a custom tab and I can view file properties. But no possibility to edit them nor to add properties to a new file.
Any hint? Is it a deprecated feature / regression? Do I have to install  something (component, ...)?
Regards.

Hi  Alain Bourgeois,
I set up an environment and tested it according to the information listed below:
http://support.microsoft.com/kb/224351
Indeed, it didn’t work when you created a new office document, office 2007 Or office 2013, I get the error shown as below:
After clicking the Detail it gives the following information:
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>
This message gives the detail information to solve this issue, but I am not a professional developer, I will continue to find causes related to Windows, if there might be any, meanwhile, I suggest to post it at the VBA forum:
