torekp 7 Report post Posted January 3, 2018 So, according to this NI document http://zone.ni.com/reference/en-XX/help/371361L-01/lvhowto/linking_vis_to_help_files/ It should be possible to link a .chm file into your executable so that a user can choose Help > Help for This VI. Well, I followed the advice, and no dice. Here is my LV2017-64bit attempt. In the development environment, it works fine, but in the executable Help for This VI is grayed out. The .chm file is a poor excuse, and unrelated to this VI, but never mind that, it's not the problem here. LV17helpEx.chm html_help_VI.vi test_help_html.aliases test_help_html.lvlps test_help_html.lvproj Quote Share this post Link to post Share on other sites
Phillip Brooks 189 Report post Posted January 3, 2018 Don't use this functionality, but the NI Doc reference has a note: Quote Note If you link from VIs to HTML files or compiled help files and you use the VIs to build a stand-alone application, you must include the files as source files when you build the application. Maybe the exe is expecting to find the help file in the support directory? Quote Share this post Link to post Share on other sites
torekp 7 Report post Posted January 3, 2018 Yes it was. However my only other option for where the .chm file goes is "same as caller", which also fails. Quote Share this post Link to post Share on other sites
Phillip Brooks 189 Report post Posted January 3, 2018 Someone reported a similar issue on the dark side. Are you using typedefs? https://forums.ni.com/t5/LabVIEW/chm-help-file-and-executable/m-p/2703303#M802558 Quote Share this post Link to post Share on other sites
torekp 7 Report post Posted January 3, 2018 Ah, thank you! I tried this guy's advice item number 7 and it worked. A bit brute-force, but maybe that's OK. (I'm not using typedefs.) 1 Quote Share this post Link to post Share on other sites
