I just realized this question should be sent to Wix-users, not to Wix-devs.
Sorry.

Betreff: Re: [WiX-devs] Removing "" from UninstallString
Hi Imri
I understand you want to use the Custom Action Type 50 to specify the path
to the executable using a property reference and then give some command
line args.
If you edited the Custom Action table directly, you would need to insert a
record in the following way:
Action: FirebirdUninstallAction
Type: 50 (+ additional flags)
Source: FBV1EXISTS (property with the fully qualified path to the
executable)
Target: /SILENT (command line arguments separately)
This would translate in Wix into:
<CustomAction Id='FirebirdUninstallAction' Property='FBV1EXISTS'
ExeCommand='/SILENT' Execute='immediate' Return='check'
HideTarget='no' Impersonate='no'></CustomAction>
If you really need to remove the leading and trailing quotes, you probably
need to code another Custom Action to format the property accordingly
since Windows Installer has no builtin operation for this. Also
consider using the 'directory' or 'file' type instead of 'raw' on the
RegistrySearch element (-> RegLocator table), then Windows Installer should
be able to interpret it as file path. (I'm not clear yet about the
details how to implement it using Wix ...)
Hope this helps you further.
Regards
Simon
