Dear  
Alsalm Alykum  
In .NET, when using the 3.9.9 SDK, the signing process looks for the `schematrons` folder in the desktop path of the user running the application. Can anyone advise how to change the path from `C:\Data\Rules\schematrons\` within the .NET application?

Thank you for your response.

My signing process works fine, but I’ve encountered an issue with the SDK version above 3.3. The signing process requires a `Data` folder to be located in the root directory of the running application (for example, on the C drive if the application is in the default Program Files directory for Windows apps).

My question is: How can I configure the signing process to locate the `\Data\Rules\schematrons` folder (and its contents) in a directory specified by the application, rather than being restricted to the root directory?

If my question is unclear or if you have any additional insights, please let me know. Additionally, could you explain why SDK version 3.3 is able to sign the document without requiring the `\Data\Rules\schematrons` folder?

We are facing the same issue, and I have sent an email that contains all the steps. I have also opened a ticket here in the community.
