Can I delete Installer folder?

My Installer folder is packed with over a Gig of -stuff-. Is it necessary to
have all that there or can I delete it all?

Hi Shell,

Good question. "Installer" isn't a standard Windows directory. It was
probably created by the manufacturer of your machine, as a location from
which to install software, maybe Vista itself, on the hard disk.

Is this a new machine? Did you get a DVD containing the Vista installation
stuff? or was Vista already installed and no DVD? If you didn't get a DVD
then the Installer directory might be your only original copy of Vista, if
you need to re-install in future.

The safest thing would be to make a backup of the Installer directory,
before you delete it. Just burn it to a DVD. Then delete the directory. But
if it's a new machine, you may want to check with the manufacturer first.

For example - when I bought a new Toshiba M400, it has a "software"
directory containing installers for all the Toshiba-supplied utilities:
about 1GB as I recall. I burned to a disk and then just deleted it. Had no
problem since - the utilities were soon replaced with updated versions on
the Toshiba website, in any case.

Hope it helps,

Thank you Andrew,

I dove deeper and found a folder in there called Managed and in there, some
numbered folders but their contents are all MS Office programs. I clicked the
Excel.exe and it loaded right up, not the installer files - the actual
program. Word did the same. When I check a WORD or EXCEl icon properties, it
doesn't give me where it short-cuts to! Maybe the instaler folder - but
shortcuts isn't telling

I found a lot of the junkware and trialware - the stuff that comes with
computers these days, residing in the other numbered folders - stuff like
Quicktime, Roxio (lots of Roxio folders!) and the most usage is behind the
four sub-folders that hold all the MS Office files
(c:\windows\installer\$PatchCache$\managed\9040110 900063BC1C8EF10054038389C\11.0.5614
(two folder like the long number each with two having the 11.0.#### and all
those with the office files.


BTW - numbers in path changed to protect the innocent


As for DVD - it didn't come with any but on first boot the system requested
2 DVDs so I could back up the installation of O/S to original factory
settings. I have a factory set Recovery" partition (D that i can't even
explore - in case I make copies of the O/S install files.

Wow, hold the phone!!

You mean the directory is actually "C:\Windows\Installer"?

Okay that's different. I thought you meant you had an Installer directory,
like "C:\Installer".

C:\Windows\Installer is indeed a standard Windows directory. Normally it is
hidden, and should not appear in Explorer. You must have selected the option
to display hidden folders.

Yes, it is normal for applications to leave *.MSI files in this directory.
That's what enables the Repair/Uninstall facility in Control Panel,
Programs. You can delete files under this directory if you want, and your
applications will continue to run normally. You just won't be able to change
or uninstall them. Leave this directory severely alone, unless you are
really tight for disk space.

If (and only if) you are really low on disk space, then you can archive off
some or all of the files from the Installer directory to another location,
such as a DVD or external Hard disk. If you want to modify, add or remove
and applications, you will need to copy the contents of the Installer
directory back, first. Otherwise you will start to get many weird error
messages when you try to install, change or uninstall applications.

But if at all possible, just leave it alone. If the applications are things
that you don't want, remove the application via Control Panel.

Thanks very much Andrew - I will leave it as it is. Though some are just
frefercne to icons and such, and the reall only filke in there is Roxio -
other than all the Office files, and maybe, that's where they are running out
of.

As they say 'You're the man'

I tried deleting all of those msi and msp files by zipping them down t
a couple of rar files and putting those on a DVD disk just in case (9
removable DVDs are marvellous). I noticed a couple of things: First
getting rid of all those files, about 1.5G in my case, didn't seem t
increase my free disk space at all, and second, it broke the trial cop
of Office 2007 Enterprise which I'm now using, and is not set to expir
until the end of October. When trying to use Word, I first saw a
installation sequence start (not unusual for trialware) and finally go
an error message that Office wasn't installed for the current user

I had also run the Tune-Up Utilities option to recover disk spac
option to recover disk space, but it had only found a few hundred megs.
(AFAIK Tune Up Utilities is the best tool out there for dealing wit
disk space issues--se
http://www.tune-up.com/products/tuneup-utilities/)

But there's a happy ending

After moving the rar files back over, and inflating them back to thei
original state, I re-ran Tune Up, and got about 8G back for a net gai
of ~6

I can't say that it was just these steps, or if I've done anything els
recently to account for it, but it couldn't hurt to try if you ar
facing the same issue. To summarize

(1) Remove the msp/msi files in the Installer folder, but save the
first

(2) Run Tune-Up Utilities procedure to recover disk spac

(3) I don't think this is necessary but would probably be a good sanit
check: try to start an Office program--it start an installation attemp
and fail

(4) Restore the files you remove

(6) Again, probably not essential at this point, but you'll need to d
it sometime anyway: Restart an Office program, which will now go throug
an installation process and succee

(7) Rerun the space recovery utilit

You should find a significant increase in available space. I'm no
sure how this worked, but surmise that when the installation files ar
replaced, the OS works out a way to use the space more efficiently
