Again, thank's to Troy for your feedback - for reference, the issue was with the way I set the package to deploy.
Following Troy's suggestion, I've spawned a
new thread - I'm looking forward to delivering functional and non-functional improvements for you all.
For those of you that have had the same issues with the install - the exe is available in the new thread, or you can extract it from the zip file in this thread - copy the file;
‘AMBReticle_1_0_0_1\ AMBReticle.exe.deploy’
out of the zip file, to a location of your choosing, and re-name the file to ‘AMBReticle.exe’.
