XP/Vista - installing apps on a common drive

On my personal workstation, I have always used a separate drive
partition for data and a separate drive partition for apps, since I have
multiple OS's and to keep partition sizes small. I point each app from
each OS to the same location, so there is only one footprint of each
installed app. If an uninstall is needed (rarely if ever), I just copy
the app folder, uninstall it, then rename the copy back to the original
so all the other OS's have it available.

I was wondering whether anyone dual boots using XP/Vista and has a
separate drive they install apps to that is common to both OS's.

Thanks,

You can do this, but the app must be installed to the exact same location
from within each operating system. Note that uninstalling the app will make
it unusable for "both" operating systems.

news:%236fDcFjDJHA.1228@xxxxxx Have you never had any problems with what you are doing there? I can think
of large applications, that I have, that have had service packs that have
changed essential registry values, and would not be able to take the update
again from another OS installation.

Also, legacy apps, that make writes to Program Files while being used, are
not installed in Program Files, with Vista.

There are probably other complications that I cannot think of right now, but
basically, why bother with all that hassle when HDD capacities continue to
increase at an exponential rate?

Disregarding media files, just a single (or two for the extra security of
RAID-1) 1TB disk will give the most hardcore multi-booting power user all
the space he/she needs.

I've never had an issue within the OS's. Any SP's will install on each
OS and everything runs fine.

The writes to the Program Files folder sounds like it may prevent this.
I'm not sure at this point which apps do and which don't.

Regardless of HD capacities, it's a waste IMO to install every app in
one OS partition and then waste the same space in another. I agree hard
drives are cheap, but if it doesn't affect an OS, it's easy to do.

On the workstation I'm putting together for someone, I have two 500 gig
drives that I was going to configure w/R1. If I can save 100 gig on
installing games to one drive, it would be worth it.

Thanks for the input, and any further comments would be welcomed.

As I stated, I prevent the "unusable" by copying the app folder and
pasting it prior to any uninstall. Then after the uninstall, I rename
the pasted folder to the name of the uninstalled folder and everything
works fine.

Is there anything Vista does or not allow to an app folder that XP
doesn't, that you are aware of?

Thanks,

news:ukOGiNkDJHA.4436@xxxxxx I still use several applications that do this, although I do not bother
using Vista on anything other than on my HTPC these days. I do use Server
2008 though, which also has UAC (WTF?).

I think this issue would probably be significant if you are using the SET
command to make change locations of Program Files, but if you are simply
choosing another location when installing the application, UAC might not
protect that folder in that way. I doubt they thought that far ahead,
seeing what a mess they made of UAC anyway.
I suppose game installations are pretty big, but I don't know why anybody
would need to have the games available in multiple operating systems.

The cost of 100GB of HDD capacity is much much less than for the time,
hassle, and possible frustration and failure of sharing the disk space, IMO.

Copying the applications folder, and then pasting it in a different install
of Windows, does NOT enable the application to be used under the 2nd version
of Windows.

What about all the files (sent to various locations in the Windows, System32
and account folders - among others) and registry entries that are needed
under "both" operating systems? The only way to get these on the operating
system is to perform an install under both operating systems.

Maybe I don't understand what you are actually doing when you say you are
"copying the app folder and
pasting it prior to any uninstall".

Unless you are speaking about programs designed for Windows 3.11 (all you
need is the application folder for the program to run) what you seem to be
stating will not usually work.

Sure it does. Since each OS is on a separate partition also, the app
folder contains all the same files. So once one OS has deleted the app,
I copy the folder back (the OS that uninstalled it believes it's gone)
and the OS's that have it installed know no different.
Yes, I do install each app under each OS. But uninstalling on one OS
doesn't remove it from the other OS's, so the only common thing is the
app folder.
I paste the copy of the app folder I made after the uninstall. That
restores the app folder for the other OS's to use.
I've been doing it for about eight years and never had an issue with
Win9x/Me/W2K/XP (started doing it with W2K).

Is there anything Vista requires that XP doesn't in regards to app
folders? If the apps are not located on C, they're not protected on
Vista, correct? These are the types of things I hope to understand
before doing this.

Thanks again,

True. The DX10 games are the only reason Vista is being considered. XP
is fine for everything else. So as more DX10 games come out, the user
might spend more time in Vista, so having all apps combined will take up
a lot less space.
You could be right there.

OK

This is the first time that you have stated that you *DO* install the app
under each instance of Windows.

That being the case, if you first copy the main application folder to
another location, uninstall the app from one of the versions of Windows and
then booting up into the alternate version of Windows - you can just paste
the apps folder back to the original location and the program will still
run.

As I said, I was not clear on what you were asking.
