How to disable MSI Windows Installer auto-repair ?

[gabri3l]

I believe your problem is related to what is called a KEYPATH in the MSI. Each component in an MSI requires a Keypath. In your case the shortcut seems to be set as a keyfile. The Windows Installer Service is trying to verify the availability of the keypath element and if it cannot find it it will Repair itself. This will hopefully fix your problem.

First check your event log. In XP it's Start-> Performance and Maintenance -> Administrative Tools-> Event Viewer And for NT Start -> Settings -> Control Panel -> Administrative Tools -> Event Viewer.

When you have your event viewer open select Application Log and find the application that is giving you trouble. An easier way can be to right click on application log and clear it. Then run the program and let it give you the repair error. Then check the log. doubleclick on the logged event and you should see something to the following
Event ID: 1004
Description: Detection of product "{4ED0C75A-8BC5-4520-B9C7-76968FD5677F}", feature "Test", component "{A7B09747-E527-4E1B-AE51-323CD636210F}" failed. The resource "C:\Progam Files\InstallSite\test.exe" does not exist.

The {A7B09747-E527-4E1B-AE51-323CD636210F} listed after component is called the Component Id. Copy that down. You can now close event viewer.

Okay, now you need to find Orca. It is included with the Windows Installer SDK. Or google for Orca.msi and look a few pages in to find a link. When you have Orca use it to open up your MSI install file.
On the left hand side of the program you see a list of tables. Scroll down and select "Component". You'll now see, in the right side, a table of components and their information including compenent id's. Find the component id's that were giving you trouble and select the KEYPATH cell. Delete the information in the keypath cell for all the component ids that were giving you trouble. Save your MSI. Now uninstall and reinstall the software using the new MSI. You should not have anymore problems.

I hope that fixed your problem. If not: Sorry for such a long post.
