Webroot is blocking my application deployment

We have webroot on some hundreds win7 machines. We are using a WDS system to silently deploy applications. Lately, not really sure what webroot agent versions that fails, it is not working anymore. The procedure is that the WDS system places a .WIM file in a download folder. From there, a DISM command mounts the wim file and then the silent installation runs.

However, once the DISM runs and mounts the wim, webroot deletes the mounted files, hence the installation fails of course. The installation then restarts after a short while by mounting the wim again. And fails. And repeats...

If we uninstall webroot, the silent installation succeeds immediately.

We have added the download path and the mount paths as global whitelist with no difference.

Any ideas, anyone?
