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 an 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. Finding withing 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”.

i want to have orca without admin please make a way for that
Dennis says
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.
Jim F says
This beats downloading the entire Windows SDK, thanks.
Champaign_Lee says
I need the product to check the stucture of the msi database. Thanks
softwaregiant says
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.
IGadget says
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.
Raymond says
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)??
Richard Pettigrew says
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.

Rajeev Kanale says
Need this tool for inspecting the installation of msi on 32 bit & 64 bit machine, and find issues.
CuLuN says
Finally iphone is doing well. thanks for the orca
LaunchCondition says
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.
Mohammed says
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 […]

Craig Steddy says
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!
