I am not sure if a software automagically becomes long file path aware by just specifying it in the manifest (which needs to be done in VS and should be done in your build system, not on a users machine). You probably need to use the new Windows API functions as well (suffixed with W or 2). See the last paragraph on https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry

Since this is known for 10 years and a fix was deemed unnecessary, one has to assume it is an intended limitation of NSIS.

Yes, no worries. Thank you! We also implemented your suggestion for futureproofness.
