BDR for endpoints Randomly fails.

BDR for endpoints Randomly fails.

I have tried on multiple machines to install the BDR delegation Service on endpoints and am met with random failures to start the service, it's been an issue for quite a while and the only suggestion I get from support is to give full access to all users to the Vembu program folder. Which is of course a huge red flag and that means the service could be replaced with malicious software.      
Is anyone else seeing this and does one else have a fix!!
