The "UninstallString" entry in Windows registry gets the path to maintenancetool as a value. However, the value is not wrapped in quotes which seems to cause troubles with paths containing spaces when launching maintenancetool via control panel / "uninstall or change a program" in an attempt to delete the application.

This problem doesn't seem to occur on all Windows 10 versions. This was tested on:

• 1803 => OK

• 1909 => OK

• 20H2 => NOK

To reproduce the problem:

1. build the "tutorial" example included with IFW
2. install in e.g. C:\Program Files (x86)\test
3. attempt to uninstall via control panel / "Uninstall or change a program"

Update: "ModifyPath" is likewise missing the quotation marks which would cause a similar problem when attempting to modify.
