Hi
I installed a SharePoint 2010 farm solution (WSP) in a test SharePoint 2013 farm and deployed it successfully.
after finished some testing and I un-installed it from the farm. Now when I open CA and try to open various pages like Farm solution , the page no longer load and got this error. this only happen to CA site. SharePoint
sites are open OK

I searched for resolution but so far notthing about this type of issue. I tried and found that by re-install this SharePoint 2010 solution back with both Compatibility Level 14 and Level 15 (with the Force parameter), so this file again
can be in 15 hive and again CA pages are now working without the error.
C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\TEMPLATE\CONTROLTEMPLATES
I fixed this but I don't think this is the right way and I don't understand why it happened neither.
Can anyone explain what this file do and how do I get this file into 15 hive without having to re-install this SharePoint 2010 the way I did to make it work.
Thanks for all advices and comments
