Creating a similar application structure to the PortableApps format

Hello, I'm new in this forum. I wanted to ask how to create the program a similar structure to the PortableApps format, but without the Source and Other folders. I don't need a lot of .ini files in order to save application settings. It would be much better to convert the existing HKEY_CURRENT_USER.txt, HKEY_LOCAL_MACHINE.txt, HKEY_USERS.txt files into one .reg file. When I launch vregtool.exe, it displays the following message: "Error processing command-line arguments: Excepted .tvr registry file." I don't know which .tvr file is excepted. I found only one .tvr file: Registry.rw.tvr, which was in Capture folder of ThinappDir.  Also, I want to the sandbox to be saved in the Data folder. I tried to modify package.ini settings and re-build the program with build.bat, but it had no effect. When I tried to open the program again, the new sandbox was created automatically named with app name.
I changed the default name of the Sandbox to Data. I also modified SandboxPath. But nothing is working, even after launching build.bat. How to fix everything? Thanks in advance.
