I've written a program using libURLDownloadToFile and distributed it as a standalone and I have included the internet library. Some of the people using the program say that clicking the button with that command does nothing but it works perfectly for everyone else. If it is just a problem with their computers how can they fix it otherwise how can I fix my code?

Hi royal745,

I am afraid that this cannot be answered without knowing your script(s) and/or taking a look at these machines

Did you add a "callbackmessage" parameter to your "liburldownloadtofile" calls and check this? See "liburl..." in the docs (=Rev Documentation).

I did set a callbackmessage and the code does seem to work on most machines but theres just a few people who say that it doesnt work for them so is there maybe something they need to get?

What is the network setup for the people who are experiencing problems? Are they using PAC files to configure their proxy servers (common at corporations)? Revolution won't automatically pick up the correct proxy server IP address if PAC files are used. This would cause your download code to fail.

sorry but thats still not it, any other ideas because I cant find anything that might cause it.

Are these all identical machines? Do the users all have the same software, and the app was installed with the same setup under the same account conditions?
This is a tricky one because there is so much that it could be on any given machine, but if the same install is working on most machines, then it seems you should be looking at those machines rather than at what changes to make in the app.
I would check the account permissions for these users. Also, do their machines have a guest account enabled? Is the app running under the correct account with correct permissions?
Do these users have a software firewall/port blocker/antivirus running? If (say) this was on windows it was run for the first time and the windows firewall popup message asking whether to unblock this app was answered with deny, then that could be it. Otherwise check the app is in the allowed list for the firewall/port blocker.
Failing that, I don't really know what to suggest, not without having a full background of the app/machines in question/environment/etc/etc which is obviously beyond the scope of this thread.
