Font Compatability with Multiple PCs

There probably is a way, but is the font in question licensed for multiple PCs/users? Which font is it and where did you get it from?

Installing a font often requires admin privileges - will the users all have that?

It seems like a lot of effort just for a font to me.

As mentioned, you likely could. The question is should you?

MS Office does what is called "font substitution" when a font is used that isnt on the computer. In other words it uses a widely used font like arial in place of the original font. If the original font is present it displays it as expected.

The problem with using a "custom" font is that there could be many variations of it with the same name. So unless you have a way to acquire the exact same font for everyone, you are most likely sticking to a widely used font. If everyone doesnt have the exact same font then it likely wont work for them anyway.

Also, its typically a bad idea to have code like this run an installation. It could freak out the user (whom unless the code warns them it will happen will likely be surprised), it could run into issues requiring an admin account to install (and potentially fail which could in turn make your code fail), it could turn out that the source of the font isnt available (at all or to that user) or it could turn out that the source of the font or the font itself becomes compromised in which case you end up helping to spread malware (which at many companies would be grounds to get fired). There are many reasons not to do this and really no good reason to make the effort to do it. The only good reason I could think of is needing to use a company wide font, in which case everyone should have it installed anyway.

I would advise you reconsider the font you are using

Taking the opposite approach, is it really necessary? Why not use a standard font?

Some people get very tetchy about applications that modify their computers. One of them is typing on my keyboard right now.

I don't think you are right about it being free, as I can find lots of licensing information online. Beware sites that seem to be giving fonts away - a lot of them are in breach of copyright. Just wanted to mention it, because it's a really easy trap to fall into.

Very wise.
