The msi peeping tom tool ORCA

So I guess that most people working with any kind of deployment has needed to look into a msi file at some time. Microsoft has released a really basic and wonderful tool called ORCA. It will allow you to look into and edit msi files ad a really low level. So how do I download it. Well Microsoft has made it available in the Windows Software Development Kit (SDK) for Windows 8.

But thats a big download for a small file, so I googled a little and found a blog article from My Server is Sick about which files you needed after downloading the minimum package. But I felt there was room for improvment. Why not just download the files you needed. So I just looked at the internet traffic of the setup program while it downloaded and saved the files.

These are the required files for ORCA 5.0.9200.16384:

Don’t trust files you haven’t downloaded from MS directly, well don’t trust hashes not directly from Microsoft either. Well if the links above are broken or you already downloaded from another source. Lets make sure the files are correct. Below are the results of a md5 and sha-1 I did of the files, so you can verify the files.
