I am using the Rational's Robot for a trial. During the recording, I got the "Unalbe to Locate DLL" java.exe error message. The message said "The dynamic link library CSH.dll could not be found in the specified path C:\...... I checked the PATH variable, and the directory for the CSH.dll file is defined. The PC that the Robot was running on has the OS Windows2000 and the Service Pack 2.
The tech support from Rational have not figured it out what's wrong.
Rational can sometimes have a dodgy install. I have come across the CSH.dll problem before but for the life of me I cannot remember what the solution was. I think there is something on their web site tech notes. However, if Rational themselves don't know (surprise surprise), then I guess it won't be in their tech notes either. I would uninstall it and re-install it again. Close everything else that is running, Antivirus stuff etc.
if it works, leave it well alone....if it does not work......ship it!
