[BUG+FIX] LoadDesktopBeforeInstall breaks after a wizard is closed

[Francesco]

Description

If a configuration wizard is closed and LoadDesktopBeforeInstall is enabled when starting the install WPI will just close and start after a reboot.

Cause

There is a bug in how WPI.hta parses the command line that triggers when the WPI window is refreshed after a wizard has been closed.

Solution

In WPI.HTA replace

	var fullpath, regexpSearch, argLine, WPIcmdArgs;

	fullpath=new String(unescape(document.location));
	fullpath=fullpath.replace("file:///","").replace("file:","").replace(/\//g,"\\\\").replace(/\$/g,"\\$");
	regexpSearch=new RegExp('^"'+fullpath+'"',"i");
	argLine=new String(oWPI.commandLine.replace(regexpSearch,''));

with

	var startQuotePos, endQuotePos, regexpSearch, argLine, WPIcmdArgs;
	argLine = oWPI.commandLine;
	if ((startQuotePos = argLine.indexOf('"')) == 0 && (endQuotePos = argLine.indexOf('"',startQuotePos+1)) > -1)
		argLine=argLine.substring(endQuotePos+1);
