uninstall infinite message box loop

[Shachar Shemesh]

This is not a good patch, as it is simptomatic. When running 
uninstaller, and the registry key does not exist, we got stuck in an 
infinite loop.

Changelog:
Shachar Shemesh <winecode at sun.consumer.org.il>

programs/uninstaller/main.c

    * Convert the "RegOpenKey" to "RegCreateKey".
