Error 2349

When installing Microsoft Office 2010 and Sharepoint 2010, I ran into some problems. The installers for each product gave the same error: "Error 2349. An internal error has occurred. ( ) Contact Microsoft Product Support Services (PSS) for assistance. For info...".

I search on Google, Bing, and Yahoo. I tried may things. None helped. Then I read the installation log in the temporary folder. Apparently the installer ran into a permission issue. It tried to write into "C:\Program Files\Common Files\Microsoft Shared". Somehow this directory is owned by "Trusted Installer", and no one has permission to write into it, not even the "Trusted Installer" itself.

So Microsoft has managed to secure the machine against its own installer, while viruses like "AV Security Suite" can install themselves even when "Microsoft Security Essential" is running. Good Job M$.

You can change the permission easily on the folder. First you would have to take the "ownership" away from the "Trusted Installer" and give it to the administrator. If you don't, everthing in the properties dialog box is disabled. Of course, this kind of "security measure" is only meant to make the ignorant feel secure. Once you take ownership, everything is enabled.Then you can change permissions on just about everything. Please may sure that you change ownership on all subfolders and "child objects" as well.

I gave full permission to the "Trusted Installer" to this folder. Actually, Sharepoint 2010 stores data files in this folder, so you really should give full permission to the current user as well. Otherwise, when you try to deploy Sharepoint packages, there will be more headaches.

After the permission chages, the installations went all the way without any problems.
