Due to a DLL name clash with Microsoft, the Citect ICMP driver ( citect\bin\icmp.dll) needs to be renamed or deleted.

This issue affects all Citect drivers using IP (TCP or UDP) to communicate.


In Citect V5.40, the ICMP driver has been renamed to CTICMP. Refer also to articles Q3214 and Q3221.

For those wanting to use the existing ICMP driver, a standalone driver install pack is available for CTICMP. Contact your local Citect Support office.
