I am trying to use a Java application on Windows 7 called "ldraw2sunflow". It converts between two 3D model formats. The program is described here. Anyway, the program ran the first time I tried it, but now ceases to run.
This is strange because the program has worked properly in the past.
Here is the error:
Jan 31, 2018 3:27:49 PM java.util.prefs.WindowsPreferences <init>
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
x80000002. Windows RegCreateKeyEx(...) returned error code 5.

Two questions:
- What is causing the error?
- Can I fix this problem without having the source code?
Thanks.
[edit]
Here is my command line: "C:\Program Files\Java\jre1.8.0_161\bin\java.exe" -Xmx1G -jar "E:\Programs Windows\LDraw\LDraw2Sunflow_f\ldraw2sunflow.jar"
[edit]
I suspect it is some type of registry issue, since when I delete "HKEY_USERS\S-1-5-21-2113055238-2099637611-63920502-1003\Software\JavaSoft\Prefs\org" using regedit, the program will start again. However the stored library paths are missing when I restart the program, so I have to type them in again. (And again, and again, and again, each time I stop/start the program.)
The actual program is failing somewhere else now:
