Thank you very much for your response. However, the issue has now evolved into the following: 

 The software runs normally when opening the default "tutorial" folder. However, when I try to open a new folder I created within the "home" directory, the application closes ("disappears") immediately. If I click to run it again, a black command-prompt-like window flashes briefly on the screen and then vanishes. Deleting my newly created folder allows the software to function normally again. The problem is accompanied by the error log shown in the new window, which contains the following message:

Error on selecting new data directory: Couldn't change directory to: D:/appdownload/SdmPsiGui-win64-v6.23/home/new

Current working directory: C:/Users/Administrator

I would greatly appreciate it if you know the solution,and I wish you a pleasant day.
