I am trying to install networker 7.5 x64 on a Windows server that already has v74 sp5 installed. I cannot  uninstall the networker v7.4 sp5 client - it does not exist in the control panel/programs add-remove list. It appears to have been a hacked install. The installer for v7.5 fails as it knows about the older version and wants it to be removed first.

“An older version of the networker software is installed. Please remove the installed version and run setup again.”

I have tried the following manual work around but this fails as well:

1. server      reboot
2. stop      networker remote exec service
3. remove      d:\program files\legato\nsr folder
4. Remove      following registry entries:

"C:\\Program Files (x86)\\Legato\\nsr\\"="1"
