How to avoid creating default registry keys inside HKEY_LOCAL_MACHINE\Software

InstallBuilder creates default registry keys for your application inside HKEY_LOCAL_MACHINE\Software\${windowsSoftwareRegistryPrefix}. windowsSoftwareRegistryPrefix is set by default to ${vendor}\${fullName}. You can avoid this behavior by setting windowsSoftwareRegistryPrefix tag to the empty string. Please find the example below:

<project>
....
<windowsSoftwareRegistryPrefix></windowsSoftwareRegistryPrefix>
...
</project>
