What is error message “Install failed. Files in use / Insufficient permissions” when installing a dll file?


If a dll file is in use, it can not be overwritten.

If a file is in use, it is definitely not missing, and probably not corrupted.

Try re-installing the program producing the error.

    My Windows 10 Op Sys displays that the CRYPTSP.dll may be corrupted and recommends re-installing it. But if it is in use I cannot. How can I proceed?
