Running from CD in Windows?

For some reason, I can’t run a windows build directly from a CD or DVD now - builds that work fine when run from the local hard disk immediately crash when run from CD. This only happens with Windows builds, works fine on Mac. I thought it might be something evil in my project, but even simple scenes do the same thing. I’ve only got XP machines here, so I haven’t tested in Vista.

My customer tells me this “used to work”, i.e. before the 2.5 upgrade. Is this a bug? Anybody else seen this problem? Am I just holding my mouth wrong? Of course, I’m trying to deliver a final, last-minute, hair-on-fire build, and this is the last issue…

Might this have something to do with the lack of long filename support for the CD format?

Maybe, but I’ve burned disks with the default OSX (Leopard) and XP disk burning utilities, as well as freeware called Burn for mac (using various formats) and from Sonic for Windows, all with the same outcome. It doesn’t look like it’s the way the disk is being burned, or what’s in the scene.

Can anyone confirm that they have done this - run a 2.5 Windows standalone build directly from CD? I note that the selector to Strip Debug Symbols is ghosted out when you choose Windows standalone from the build settings dialog, could this be related, i.e. it’s trying to write a debug log to it’s local path, from the CD?

you can not run it from a non writable device as there are temporal files written out for logs and alike which can not be written to a disk.
The debug symbols is not related to the log, the log is always written when the player is executed to trask startup etc. Thats very much needed for you as your users otherwise can not tell you at which point of startup it crashed for example.

The only way to run it from disk is putting a webplayer + html on there, which would basically force the player to use the browsers cache folder.

Really? No way to turn off the requirement to write locally? Running from an optical disk works fine on a Mac, and I’m told it used to work on Windows. What’s up with that?

(or something like that) will help you in this case?

Concerned about… :roll:

Go back to previous Unity version (2.1 I think).

It’s fully compatible with 2.5 and it works from CD/DVD.

Hope this helps.

Unless of course you are having trouble with localization issues which are fixed in 2.5.

In which case you are boned … like me.

Just to get this straight: you’re saying that any build if your project you create with Unity2.5-windows, won’t run, if you place that build on a non writable medium like a cd?

If so, please file a bug, and post the bug number in this thread for reference.
