It may not help dramatically with this particular issue, but having the game (any game actually) outside of what Windows sees as a 'protected system area' is proven to reduce the potential for problems.
https://support.steampowered.com/kb_art ... -YUBN-8129 details the official way of doing this, so it's not something that isn't given support by Steam.
I'd strongly suggest you do this first, even if it doesn't *fix* this problem of the installer not working properly it
will save you grief in the future.

You're half way there then!
If you use either of those archive managers to look at the contents of the .ap package you'll find that you're basically looking at a .zip file under a different name that merely contains the directories and files that the game reads to load the models---nothing special, nothing complex. The game reads the .ap archives natively, needing no other intervention from the users to be able to do so.
The move to .ap packages made distribution and installation of DLC easier and quicker but unfortunately brought a lot of confusion with it. The forums are full of rubbish written about .ap's--as I've written my share of that rubbish I feel qualified to make the statement
If you have files *mirrored* outside of the .ap --same file name, in the same directory structure-- these are used in preference to the archived copy. This is very handy if you wish to change something in the default model, as working on this external copy means that when (not if) you make a pigs ear of it you still have the untouched original (and working) file to revert back to.
So, whether you move Steam or not, open the Class52Pacl01Assets.ap package with either WinRAR or 7-Zip, drill down the folders till you get to the default models "Engine" folder. All you need to do is drag and drop the .GeoPcDx file (I don't have the DTG 52 so can't be specific with the file names) into one of the new Armstrong Powerhouse installed loco's "Engine" folder.
Then simply copy and paste this file into the others. If there's still a "Default" folder outside of the .ap this will only contain the files that the sound pack uses instead of the DTG versions, so will not need the .GeoPcDx file putting in there.

This is
only needed to allow RW Tools to manipulate the files, not to enable the game to use the files.
