Receiving INCOMPATIBLE_CLIENT error after upgrading from 20.2.1 to 20.2.3 AutoVue EM. Any advice?

Hello,

Updated AutoVue Electro/Mechanical client server edition from 20.2.1 to 20.2.3.  Now I cannot connect from clients.

Receive the following:

Initialization failed.  INCOMPATIBLE_CLIENT

Client and server versions do not match

client = 20.2.1

server = 20.2.3

An error occurred while connecting to the server.

Restart the applet?

Yes     No

A restart results in the same error once again.  Has anyone else seen this or know what I may have missed during the update?

Thanks in advance,

Joanna
