For some reason I have a mental block and can’t seem to remember this, but instead of using dism to install language packs on Windows 7 or above, like this…
dism /online /add-package /packagepath:<path to language pack .cab file>
…you can also simply rename the .cab language pack file to have the .mlc file extension and double-click it.
There’s yet another way too, and that’s to run the lpksetup.exe utility and point it at your .cab file I think. Haven’t tried that though as I think the .mlc method is easier.
I’m writing with reference to a colleague’s blog post where he has found a very useful fix for a very annoying start up and log-on delay issue in Windows 7 SP1. Here’s his post, worth a read:
We were finding that computers in shared areas which had been logged on by many users (i.e. 50+ user profiles) were experiencing massive delays starting up and logging on. Until he found the fix the only solution was to leave the computers on all the time, or get them to start up really early in the morning.
One fix we tried was removing all the user profiles from the computers, and this only worked some of the time. Then my colleague found the right hot-fix and all of a sudden our startup and logon times dropped back to a few minutes. Big relief!
Here’s the relevant hotfix: http://support.microsoft.com/kb/2617858
See the blog entry (linked above) for a detailed explanation.
I finally realised where to get hold of version 5 of Orca – the one most suitable for Windows 7 able to validate .msi files for Windows Installer 5. It was of course in the Windows SDK for Windows 7 and .NET Framework 4. Unfortunately there’s no mini-download for the msi sdk like with version 4.5, so for simplicity I’ve acquired the .msi for orca and put it online for download…
Orca 5.0.7693.0 (2.1MB)
If you would rather download the official version from Microsoft you need to install the debugging tools from the Windows SDK, then go in to Program Files\Windows SDK\7.1\Bin and orca.msi will be in there.
