Host Integration Server: String was not recognized as a valid DateTime while open HIS Configuration Console

This week I installed on a BizTalk Server 2016 environment Host Integration Server 2016 (HIS), and to my surprise, I was receiving this quite unusual and annoying error: String was not recognized as a valid DateTime.

Host Integration Server (HIS) Configuration Console: String was not recognized as a valid DateTime

Each time I try to open the HIS Configuration Console.

Nevertheless, this error did not occur the first time I ran the configuration console, in other words, after I install the HIS, the first time I executed the Configuration console everything worked ok. Even, if I close and open again, everything was still working fine. The problem only occurred once I actually configure something.

This error only occurred If:

  • I configure let’s say all the HIS features;
  • Close the HIS Configuration console
  • And then try to open the Configuration console again


As far as I know, there is no other reason, this is a bug!


The solution is very simple:

But in fact, there is already Host Integration Server Cumulative Update 2 available so I will recommend you installing this one instead:

After installing HIS CU2, everything worked as expected.
