["Could not load file or assembly 'System.Transactions Version=4.0.0.0" During Pulseway Manager installation]

Hi there,

 

I installed Pulseway Manager 64-bit on a Windows 2008 R2 64-bit server.

I can open Pulseway Manager without any issues. But once I fill in my account details and press " Validate Account " I get the an error as shown in the added image.

 

I've already installed Pulseway on about 20 servers ranging from 2012 R2, 2008 to 2003 32-bit without issues using the same credentials.

 

Does anyone know what causes this error and a possible solution? Help would be much appreciated.

 

Thanks!
