I have an isolated shell application. I don't want some extensions to be displayed under tools->extension and updates.So I have tried removing the following lines for the property "PkgDefSearchPath" from pkgdef file
$ShellFolder$\Common7\IDE\ShellExtensions; \
$ShellFolder$\Common7\IDE\CommonExtensions; \
After that, while launching my application it is throwing me an error
"Cannot find one or more components.Please reinstall the application".
