Not quite, they do update, they just have additional options, or at least the alphas seem to have always worked that way.
I've seen no change to this at all. Both copies attempt to overwrite everything that has been altered, but leave other stuff untouched, including in the portable version all the add ons and settings.
The only differences in working are as stated that it can only do stuff the user its installed for is allowed to do, since its not usually the admin and has security protocols to uphold given as Brian says, it can be copied off to anywhere.

This is why it can even run on a CD as you just move the whole folder to the writing area for the cd, but it is very slow, I know I tried it!


I guess the next question will be if we can run it on a remote drive over the web. I'll pass on that one.

Subject: Re: [nvda] Portable copy


It's possible to make and run a portable copy of NVDA (or any other program that has a portable variant) from any media of your choosing.

Although portable variants are intended to be, well, portable the two things that determine that they truly are:
1. They're placed on media that can be carried with you, e.g., a thumb drive, SD card, external HDD.
2. They do not install, and by that I mean in the literal sense. Installed programs make entries in the Windows Registry and also often either add libraries of their own into the existing collection or rely on libraries from it. Portable variants do neither of those things and everything they need is self-contained in the folder structure created.

The NVDA installer (whether a fresh one downloaded from NVAccess, or the built-in auto update function) does not update portable copies. If you want updated portable copies you need to have NVDA make new ones for you.

So, yes, you can create a folder such as C:\Portable_Programs\NVDA and create a portable copy of NVDA there, and it will remain there, and can be run from there, and it will never be updated unless you update it. You can also, at the same time, have an active installed version of NVDA on the same machine. Some people create portable copies of whatever version of NVDA it is that they currently have running, and do so in a dedicated folder on their hard drives, immediately prior to updating to a new version as an "insurance policy" against possible issues.

By the way, once you have a portable copy on anything, the root folder can be copied over to as many other places as you might wish, and you have additional portable copies since all pieces needed to run a portable copy are contained in the folder structure.
