Orca MSI Editor allows you to edit the properties of any MSI file. With this tool, you can change the title and text within the installer and look at how and where the files are delivered. It’s also handy if you need to “hack” an MSI to work with a newer version of Windows.
This tool used to be a part of Microsoft Developer Tools but is now retired and no longer supported by the company. Since finding the Microsoft Developer Tools is such a chore, I have made a download available with just the Orca MSI Editor tool.
Click here to download Orca MSI Editor then install it. Once installed you can right-click any MSI and select “Open with Orca”.
Thanks a lot for sharing this.
The version here is VERY old. I have version 5 from 2012 (signed by Microsoft). How can I send it to you?
Thank you, it’s really working!.

This is a great tool. However it needs protection from misuse
does it required an admin access to install ?
Still works, thanks for providing this :-)

When I open bluestacks using orca, it says ” Failed to open MSI Database ”
.
Please help
Thanks
i want to have orca without admin please make a way for that
Still a great tool for peering inside an msi file to see what version it is.
I downloaded a Google Admin file claiming that it was version 1.2 when it was version 1.1.
No wonder it did not update me to the latest version – Bad Google, Bad!
Is there any useful data on using orca? More specifically to modify a msi file so that it contains user input such as a user name and password automatically.
This beats downloading the entire Windows SDK, thanks.
I need the product to check the stucture of the msi database. Thanks
It works ok. Go to the release folder where you created your executables. Right click on the msi file and choose the new “edit with orca ” option. To highlight an entry I use the keys to create a pointer to the component. Anyway my use of this nifty program is limited.
Make a backup of your MSI and then edit that. Use “Save”, not “Save As” to ensure all the bits are kept. then look in the tables for LaunchConditon or *ExecuteSequence for what you need. there are other places but those are the main ones. It may take several attempts.
I have the MSI file which will install the program.
How to make in the MSI file by using ORCA so that the program (exe file after install) can be run in compatible mode for windows 7 or XP (SP3)??
This doesn’t appear to be entirely accurate for the latest version of the MSI you can download from LogMeIn.
(as of the date of this post)
The Fields within the tables refered to in the article no longer exist in the MSI I downloaded today.
I am trying to figure out what to change myself to get this working, but any further pointers would be appreciated.
This is awesome. works great on windows 7 64bit too..
Need this tool for inspecting the installation of msi on 32 bit & 64 bit machine, and find issues.
Finally iphone is doing well. thanks for the orca
If you’re trying to install an MSI onto an “unsupported” operating system–
1. Use ORCA to open the MSI
2. Find the line labeled “Launch Condition”
3. Delete all the value or try modifying them but likely you aren’t qualified to if you need these rudimentary instructions
4. SAVE THE NEW MSI AND PREFERABLY AS A COPY INSTEAD OF OVERWRITING THE ORIGINAL JUST IN CASE YOU BORKED UP SOMETHING ELSE OR DELETING THE LAUNCH CONDITIONS (UNLIKELY) BREAKS IT AND YOU’RE BETTER OFF TRASHING A NEW COPY INSTEAD OF BORKING YOUR ORIGINAL.
Very useful and fruitful in controlling msi files.
thn in this folder, which install the actual Orca tool. Update: Several people have mentioned this link, where you can download Orca directly without having to download and install the Microsoft Windows […]

I’m surprised that anybody still uses Orca. There is a free alternative MSI editor that owns it called InstEd. It’s available at http://www.instedit.com
Downloading Orca trying to create custom dialogs for setup.
Wicked tool!
