Crash on starting installer on Win7 without a C Drive

[ghost]

There is a crash in the installer when starting it on Windows 7 if there is not a C:\ drive on the machine. This happens immediately after the information message prompting the user to select a permanent installation path. The current work around is to add a C:\ drive to the machine (inserting a USB flash device, for example) allowing the user to continue to choose a installation path on another drive.

Error message:

Could not find a part of the path 'C:/GeDoSaTo'

Crash details:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
