Install Tomcat 5.0.28 failed

Answer 1

Not sure if this is related, but I vaguely remember having issues with Tomcat when I installed it on a path which included empty spaces. ie. the space in between "Program" and "Files" in your Tomcat installation path in C:\Program Files... may be the cause for the issues.

I might be completely off the track though. Let us know if this helps though.

Answer 2

I agree with tim_wonil that the issue is probably a bad path somewhere.

As far as nsExec goes, .dll files are normally NSIS plugins and the nsExec plugin makes a copy of itself and patches that copy so it will run as a program and not a dll. You can find the nsExec source @ NSIS SCM
