This is the answer from the support team :
Actually, the macro is not the point. It does the same thing with this html file :
“File not found”. I’m not using access point but the ‘open in server’ facility of the Qlikview executable.
It works when I ‘open’ it directly. I need to provide the URL as “relative”, not as “absolute” location.
It appears that if you want to use relative paths, the folder must be under wwwroot\inetpub for IIS or you have to set the path in our webserver virtual folders,
Relative mean relative to where the web server is looking for it.
In conclusion, the absolute path, with IP of server, must be used.
