Method 1: Copying the Iviresizew7.dll File to the Windows System Folder 

1. The file you downloaded is a compressed file with the ".zip" extension. In order to install it, first, double-click the ".zip" file and open the file. You will see the file named "Iviresizew7.dll" in the window that opens up. This is the file you need to install. Drag this file to the desktop with your mouse's left button.

   

2. Copy the "Iviresizew7.dll" file and paste it into the "C:\Windows\System32" folder.

   

3. If your operating system has a 64 Bit architecture, copy the "Iviresizew7.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 "Iviresizew7.dll" file into both folders.

   

4. In order to run the Command Line as an administrator, complete the following steps.

   NOTE! In this explanation, we ran the Command Line on Windows 10. If you are using one of the Windows 8.1, Windows 8, Windows 7, Windows Vista or Windows XP operating systems, you can use the same methods to run the Command Line as an administrator. Even though the pictures are taken from Windows 10, the processes are similar.

   1. First, open the Start Menu and before clicking anywhere, type "cmd" but do not press Enter.
   2. When you see the "Command Line" option among the search results, hit the "CTRL" + "SHIFT" + "ENTER" keys on your keyboard.
   3. A window will pop up asking, "Do you want to run this process?". Confirm it by clicking to "Yes" button.

   

5. Paste the command below into the Command Line that will open up and hit Enter. This command will delete the damaged registry of the Iviresizew7.dll file (It will not delete the file we pasted into the System32 folder; it will delete the registry in Regedit. The file we pasted into the System32 folder will not be damaged).

   %windir%\System32\regsvr32.exe /u Iviresizew7.dll

   

6. If you are using a Windows version that has 64 Bit architecture, after running the above command, you need to run the command below. With this command, we will clean the problematic Iviresizew7.dll registry for 64 Bit (The cleaning process only involves the registries in Regedit. In other words, the dll file you pasted into the SysWoW64 will not be damaged).

   %windir%\SysWoW64\regsvr32.exe /u Iviresizew7.dll

   

7. We need to make a new registry for the dll file in place of the one we deleted from the Windows Registry Editor. In order to do this process, copy the command below and after pasting it in the Command Line, press Enter.

   %windir%\System32\regsvr32.exe /i Iviresizew7.dll

   

8. If you are using a Windows with 64 Bit architecture, after running the previous command, you need to run the command below. By running this command, we will have created a clean registry for the Iviresizew7.dll file (We deleted the damaged registry with the previous command).

   %windir%\SysWoW64\regsvr32.exe /i Iviresizew7.dll

   

9. You may see certain error messages when running the commands from the command line. These errors will not prevent the installation of the Iviresizew7.dll file. In other words, the installation will finish, but it may give some errors because of certain incompatibilities. After restarting your computer, to see if the installation was successful or not, try running the software that was giving the dll error again. If you continue to get the errors when running the software after the installation, you can try the 2nd Method as an alternative.

Method 2: Copying the Iviresizew7.dll File to the Software File Folder 

2. Open the software file folder by clicking the Open File Location button in the "Properties" window that comes up.

   

3. Copy the Iviresizew7.dll file.
4. Paste the dll file you copied into the software's file folder that we just opened.

   

5. When the dll file is moved to the software file folder, it means that the process is completed. Check to see if the problem was solved by running the software giving the error message again. If you are still receiving the error message, you can complete the 3rd Method as an alternative.
