Hi Ryan
Thanks for the feedback.
I did as you asked and then checked I could access the FM admin console, which was OK. I then tried to reinstall but got the same error. The installation process seems to go smoothly as indicated in the messages in the java window until the process tries to restart the IIS Web Server.
OK, scrub that.
On further investigation, in IIS Manager although the FMWebSite service had started, the Default Web Site was stopped. After starting this site I reran the installation which then succeeded.
Lesson learnt: check all services that need to be running are running first!
Many thanks for you help, though.
Karl.
