Can't call Uninstall Override during Uninstall process

I've put together my first setup project that calls a Custom Action to run a clean up process during an Uninstall. The problem I have is that my Uninstall override is never called. it just calls the Install and Commit overrides again?

Can anyone point me in the right direction as where I might be going wrong?

It sounds similar to this http://support.microsoft.com/kb/906766/en-us - is this a RemovePreviousVersions upgrade?

Unfortunately my install is run from scratch without any previous versions installed. This is the first version of my installation.

I just can’t understand why, when running an uninstall, the Commit and Install overrides are called but Uninstalled is never triggered?

I've found the reason for my strange effect, but I'm still in need of a solution. If I try to pass multiple parameters the Commit and Install are called twice during the Installation and the Uninstall is never called. If I pass just one parameter the Commit and Installed are called just once and Uninstall called once as required.

When I pass multiple parameters in CustomActionData, I'm space separating them and if I debug the Custom Action DLL I can see the values of my parameters and they are all valid and passed correctly.

Here's my CustomActionData entry...

/INSTALLTYPE=[INSTALLTYPE] /TARGETDIR="[TARGETDIR]\" /WindowsFolder="[WindowsFolder]\"

So am I passing the parameters incorrectly??
