You will have to edit the footer select code.

look at the quickchooser code in the footer template once it's installed and replace it with the code from the default theme for 4.2.2.

<vb:if condition="$show['quickchooser']">
			<select name="styleid" onchange="switch_id(this, 'style')">
				<optgroup label="{vb:rawphrase quick_style_chooser}"><option class="hidden"></option></optgroup>
				<vb:if condition="$quickchooserbits1">
					<vb:if condition="$quickchooserbits2">
					<optgroup label="&nbsp;{vb:rawphrase standard_styles}">
					</vb:if>				
					{vb:raw quickchooserbits1}
					<vb:if condition="$quickchooserbits2">
					</optgroup>
					</vb:if>					
				</vb:if>
				<vb:if condition="$quickchooserbits2">
					<vb:if condition="$quickchooserbits1">
					<optgroup label="&nbsp;{vb:rawphrase mobile_styles}">
					</vb:if>
					{vb:raw quickchooserbits2}
					<vb:if condition="$quickchooserbits1">
					</optgroup>
					</vb:if>					
				</vb:if>
			</select>	
		</vb:if>

The change was at 4.1.12 with the theme selector.

This is what you will need to replace with the new code.

<vb:if condition="$show['quickchooser']">
				<select name="styleid" onchange="switch_id(this, 'style')">
					<optgroup label="{vb:rawphrase quick_style_chooser}">
						{vb:raw quickchooserbits}
					</optgroup>
				</select>
			</vb:if>

There will be a few more things to address but that will get it to a usable state.

I tend to install them and then rebuild them on a fresh vb for the current version of vb that the client has installed. The biggest issue is the mods as they are version specific but with most you can get away with using an earlier version of a mod, but if you are using multiple styles it can be problematic.. Nothing that can't be sorted within the style but a pain in the butt to get through. It's easier to just install an older one and then rebuild it on a fresh default style.
