  3. If your operating system has a 64 Bit architecture, copy the "Qt3.dll" file and paste it also into the "C:\Windows\sysWOW64" folder.
    NOTE! On 64 Bit systems, the dll file must be in both the "sysWOW64" folder as well as the "System32" folder. In other words, you must copy the "Qt3.dll" file into both folders.
    Pasting the Qt3.dll file into the Windows/sysWOW64 folder
    Step 3:Pasting the Qt3.dll file into the Windows/sysWOW64 folder
  4. In order to complete this step, you must run the Command Prompt as administrator. In order to do this, all you have to do is follow the steps below.

  5. Let's copy the command below and paste it in the Command Line that comes up, then let's press Enter. This command deletes the Qt3.dll file's problematic registry in the Windows Registry Editor (The file that we copied to the System32 folder does not perform any action with the file, it just deletes the registry in the Windows Registry Editor. The file that we pasted into the System32 folder will not be damaged).
    %windir%\System32\regsvr32.exe /u Qt3.dll
    Deleting the Qt3.dll file's problematic registry in the Windows Registry Editor
    Step 5:Deleting the Qt3.dll file's problematic registry in the Windows Registry Editor
  6. If the Windows you use has 64 Bit architecture, after running the command above, you must run the command below. This command will clean the broken registry of the Qt3.dll file from the 64 Bit architecture (The Cleaning process is only with registries in the Windows Registry Editor. In other words, the dll file that we pasted into the SysWoW64 folder will stay as it is).
    %windir%\SysWoW64\regsvr32.exe /u Qt3.dll
    Uninstalling the broken registry of the Qt3.dll file from the Windows Registry Editor (for 64 Bit)
    Step 6:Uninstalling the broken registry of the Qt3.dll file from the Windows Registry Editor (for 64 Bit)
