Yes, SourceDB+ is still supported with iNoise.
SourceDB+ requires full read and write access to the license file. When iNoise is installed in the default Windows program folder:
C:\Program Files\
Windows may restrict the required access. As a result, SourceDB+ may not work correctly from this location.
Copy the complete iNoise program folder to a location where you have full read and write access, for example:
D:\DGMR\iNoise\
After copying the folder, start iNoise and SourceDB+ from the new location.
Alternatively, you can copy only the files required by SourceDB+ to a location where you have full read and write access.

the user has full read and write access. Avoid running SourceDB+ directly from
a protected Windows folder such as C:\Program Files.
If SourceDB+ still does not work after moving the files, please contact DGMR Software Support and include:
