The version is 4.9.1014.0. This used to work.
DataMaker 4.9.1014.0.
The log file just say the session started, no other information. The ProcMon file provided had a lot of FILE LOCKED WITH ONLY READERS and the Operation is CreateFileMapping with the path that points to C:\Windows\System32\wow64.dll. This is DataMaker 4.9.104.0.
Rebooting the server resolved this issue. There might have been some Windows file locks that got freed up after rebooting.
