Office 2007 Local Installation Source

Post by Vista Ultimate R2 »

I was just installing some more Office 2007 programs and removed the last bits of Office 2003 that I still had left, and noticed that the C:\MSOCache folder is occupying over 800 MB of hard disk space. This is where Office stores the "local installation source", which is basically a copy of the installation CD, and you always used to be able to delete this using the Disk Cleanup Wizard (the result of which was that you would have to insert the Office CD when updating Office). However, this MSKB article says that the option to remove it is no longer available with Office 2007 (yet gives no reason for this), and in another KB article (relating to Office 2003) it says that you should only delete these files using the Cleanup Wizard, not manually using Explorer. I would like that gigabyte back though as my hard drive is nearly full, so what's your opinion on just going ahead and trashing that entire folder manually?

Id say just trash it. If they're only temporary files it won't hurt.

For the betas I used explorer and deleted the setup files, there was no errors. I'm pretty sure nothing will happen but you probably won't be able to uninstall office or change it.

OK then, thanks for the opinions, I just wanted to make sure that there wasn't a good reason why Microsoft had removed the option to delete these files for the 2007 release, and also said that you shouldn't manually delete that folder (eg that it becomes impossible to install updates or something like that!).

By the way, talking of Office updates, why does Office 2007 not appear on MS Update? Even if there aren't updates available for it (which there aren't yet, as far as I know), you'd think it would be listed in the bit on the left where it lists products that it's searching for updates for. When I still had some Office 2003 programs installed that was listed there, but now it just has Windows and SQL Server (even though I don't have SQL Server...). Unless they just haven't got round to adding Office 2007 to MS Update yet?

No, you're probably confused about why a local installation source is required.
See, in Office 2000, XP, and 2003, you had the ability to create an administrative installation point using the /a switch on setup.exe. All it did was extract the installation files out of the .cab files (2000 didn't use cabs) and this was done so that customizations to settings, programs installed, or even slipstreaming of updates could be done.

In the 2007 Office System, they changed how you can customize installations. You now run the Customization tool (setup.exe /admin) which would allow you to create a .msp file that can be used to customize and automate installation. Which also means slipstreaming updates is not an option anymore, since they simplified the process by giving you an \Updates folder to drop any .msp files (except the ones created with OCT) which setup applies after installing the product.

I recommend you don't remove it unless you're really out of disk space, and removing it the wrong way could screw up adding features or repairing.
