You can try to find the Product Code of this installation in registry
(under SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall) and run the
uninstall like this:
Msiexec /x {PRODUCT-CODE-GUID-HERE} IGNORE_PRE_CHECK=1
Hope this helps,

Subject: [WiX-users] How to uninstall the program if I made such mistake
Hi,
I'm working on some setup project.
I built my project, run the msi, and get the product installed.
I made some change on the code, rebuilt it again, run the msi, and got
error "another version is already installed, please use ARP ..."
I went to the ARP in control panel, find my product, click Uninstall...
The, the terrible error message box comes out:
Windows Server 2008 is required. Blablabla...
This is the error message I defined and used in launchcondition, the bad
thing is I've forgot to add "Installed OR" in the condition expression!
<Condition Message="!(loc.Error_Prereq_OSVersion)">
<![CDATA[(IGNORE_PRE_CHECK > 0) OR (OS_SUPPORTE_UI AND VersionNT
>= 600 AND WindowsBuild >= 6001 AND MsiNTProductType =3)]]>
</Condition>
IGNORE_PRE_CHECK is a property I used temporally, to make the setup work
in my dev machine (it's win7).
So I can install/uninstall it by
Msiexec /i (/x) setup.msi IGNORE_PRE_CHECK=1
But now, I don't have the original msi anymore and can only remove it
from ARP. What should I do?
Thanks,
-Elfe
