Question
Debug operations in Keil have suddenly started hanging during programming and the CPROGACMP window does not close. How do I fix this?
 
Answer
This issue occasionally appears in Windows 10. It is caused by an entry that is added to the Windows registry that prevents the progarmcortex_dll.dll file from unloading after programming is completed. This issue can be resolved by doing the following:

1. With administrative access, open regedit.exe. This can be done from the Windows 10 start menu or by opening a Run window and opening "regedit.exe".

2. Navigate through the folders on the left side to find the following path: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

3. On the right hand side there should be an entry with a name that matches the file path to the Keil UV4.exe application. The data should read "$ IgnoreFreeLibrary<progarmcortex_dll.dll>". Right click this entry and delete it.

4. Close and reopen Keil.
