This happened once before and someone pointed me to this:https://www.lifewire.com/how-to-change-file-associations-in-windows-2624477. it worked before but not this time. Now, when you see the list of file extensions, there is no grey box to choose the associated program, instead there is either a blue box which will only take you to the Microsoft store for .cdp and an option to associate TANE with.cdp2, which doesn't seem to do anything. Is there another possible way to fix this. it's minor but very annoying.
 
  1. On the Windows Start menu, select Settings > Apps > Default apps.
  2. Scroll down to select Choose default apps by file type
  3. Scroll through the alphabetical list to see what has now hijacked .cdp and probably .cdp2
  4. Click on the offending app for .cdp and select TRS19.exe from the options (this assumes that TRS19.exe is registered with your windows as using the .cdp file type)
  5. Repeat for .cdp2 if it has also been hijacked.
 
Doesn't work. The only available options are to find the app on the Microsoft Store. Boxes with options are grey with + signs which give you a list. The boxes for .cdp and .cdp2 are blue and only allow you to search the Store.

OK, try this


  1. Right Mouse Click on the .cdp file icon.
  2. Select Open With from the menu
  3. Select More Apps
  4. Scroll down the list - if TRS19.exe appears then select it. If it does not appear then scroll to the very bottom and continue with the steps below
  5. Select Look for another app on this PC
  6. Navigate to your N3V Trainz TRS19 drive and folder
  7. Select TRS19.exe
  8. Click Open

The strange "not Trainz" icon should now be replaced with the strange "N3V Trainz" icon.

If the above does not work then, worst case scenario, you may need to reinstall TRS19.
 
That got the TRS19 icon there at least. Don't know where the cdp icon vanished off to or what caused it to disappear in the first place.
 
Icons are cached and the cache gets corrupted. This can affect all applications and even files associated with them such as acrobat reader files suddenly not having the acrobat icon.

There's a way to clear the cache and rebuild it.

Exit all running programs.

You need to open up a command prompt with admin privileges.

Press Win +R to bring up the Run box.
Type in cmd and check the admin box.

You'll get a confirmation with are you sure you want to do this.

Click on Yes.

In the box, type the following commands one at a time. Remember to press Enter after each line.

taskkill /IM explorer.exe /F


DEL /A /Q "%localappdata%\IconCache.db"


DEL /A /F /Q "%localappdata%\Microsoft\Windows\Explorer\iconcache*"

When done, close the window and reboot.

If you want to be totally geeky, you can automate the reboot by typing in.

shutdown /r /f /t 00

And even more geeky by taking all the above lines and putting them in a .cmd batch that you can run by double-clicking on when things get stuffed. The issue is rare enough, however, that this may not be necessary.
