If the installation cannot replace the existing EXE file, an access denied error may appear. Running application, concurrent installation, or folder access are among the possible causes.

Basic approach

Windows may prevent modification of a running file. Even if the window appears to be closed, the background process may be continuing. IPScans+ 4.1.1 installs versions in separate directories, reducing the need to overwrite the old executable and preventing concurrent installations.

Application steps

  1. Close multiple installations in progress; If there is an open work in the application, save it.
  2. Close the application normally and launch the updated official installation package once.
  3. If you are repairing the same version, make sure that version is turned off; If the error persists, review the full path in the installation log.

Practical example

If the error occurs when replacing the old IPscans-Plus.exe file, the skip file option may mix old and new components. Instead of considering the installation complete, make a clean retry and check the version of the opened application.

Interpret the result correctly

Turning off security software or giving everyone full permissions to the folder is not a general solution. If installation issue persists, get support via log, version and file; Do not delete personal files. Running as administrator does not solve the locked file problem in all cases.
