I have a SP2010 solution that I deployed to SP2013 (add-spsolution, install-spsolution). The controltemplates installed to the 14 hive, but when I load a page in my site, I get an error that my controls can't be loaded. When I look at the log files, I see that SharePoint is trying to locate them in the 15 hive. How do I tell SharePoint to look in the 14 hive instead?
At this point, we don't want to recreate the 2010 solutions, just deploy them and get them working.
