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.
Download Orca MSI Editor then install it. Once installed you can right-click any MSI and select Open with Orca.
This tool used to be a part of Microsoft Developer Tools but is now retired and no longer supported by the company. Use it at your own risk. If you’re going to link to the file from your website, please link to this page and not the file directly, otherwise I’ll have to remove it.

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.
