@Anders Thank you for your help but I don't understand it.
I appreciate your advice that NSIS will do both user and admin installs and there are issues that need fixing so your other advice is a bonus. The installer is in an open source project written 5 years ago and updated by a different user each year all long gone, probably linux users with little interest in Windows.
The
NSIS Menu is confusing and eventually I noticed the
wiki Simple tutorials link (which I tweaked to make a little clearer). It clearly explains the process for compiling scripts and got me started.
- I assume I need to rework the script to include most of the code you provided (?)
- There are no HKCU commands in the script so I don't understand that comment but I note the code you provided fixes $PROGRAMFILES
- I don't know what comprises the version check or why it is required
