The software installation process may overwrite common system files such as dynamic link libraries (.dll files) and executable files (.exe files).
Steps
Step 1. The absence of the required DLL files can lead to system malfunctions, for example, improper shutdown of its work
Run a system drive scan using Norton WinDoctor, which automatically repairs your system. If you uninstall Norton products, we recommend that you keep the Norton WinDoctor and Norton Speed Disk (defragmenter) utilities.
Step 2. Before launching files downloaded from the Internet, always scan them
Remove programs you are not using. A large number of installed programs clogs up the system. Defragment your hard drive regularly. As a result of repeated write / delete cycles, files on the hard disk begin to be arranged chaotically (that is, the hard disk becomes fragmented and starts to work slower). When overwriting system files, for example,.sys,.dll,.ocx,.ttf,.fon,.exe files, programs malfunction and the system may crash.
Step 3. If you have determined that you do not have one or more DLL files, they can be restored
On the Internet, find sites offering free DLL downloads. Download and unpack the DLL file (s). To unpack the archive, you need a Winzip or WinRAR archiver program.
Step 4. Now you need to copy the DLL file to the appropriate folder
Enter the name of the DLL file in the search engine and read the recommendations on which folder to copy it to.
Step 5. This figure provides an example of where to find the destination folder recommendations for the q_encutl.dll file
Step 6. For example, consider this message from the Norton WinDoctor utility
"C: \ Program Files \ Common Files \ InstallShield \ Professional \ RunTime \ 0701 \ Intel32 \ DotNetInstaller.exe cannot access a necessary file, mscoree.dll." In this case, download the mscoree.dll file.
Step 7. Then locate the Intel32 folder (according to the path given in the message of the WinDoctor utility), open it and copy the mscoree.dll file to this folder
Step 8. Or open the Run window
Enter SFC. If that doesn't work, enter the name of the missing DLL file and manually overwrite it from the Windows installation disc.
Advice
- If you don't have an archiving program, download it for free from
- Sometimes software (software) comes with a set of DLL files included, so installing such software can restore missing DLL files.
