If you have been using Windows for a long time, then CCleaner is no stranger to you. It is a computer utility program that is used for cleaning the potentially unwanted files and invalid Windows Registry entries from a computer. By cleaning the temporary and unwanted files it makes your computer more secure and faster. But there can be a problem with running this software; like a situation where the user keeps clicking it to open but it just won’t open or appears then vanishes back.

Fix: CCleaner won’t Open - 1

CCleaner won’t open

What causes CCleaner not to open?

According to our investigation, this sort of issue happens because of malware on your system or after the malware is cleaned out by the security software on your system, but it has already done its damage. These malware use some registry hack where it will prevent you from opening certain apps in your computer.

We will solely focus on the registry editor in the solution because that is where the problem is causing for the software that we are trying to open. And we will solve that in the solution below.

Removing the CCleaner entries from Registry Editor

Here we will be providing a solution where you can get rid of these affected registry files of certain applications that you are facing the problem about. In our case, it’s the CCleaner which won’t open no matter what you do. But the same thing can happen to other applications which we will use in this solution. Moving on to the steps:

  1. Hold Windows Key and Press R to open Run , then type “ regedit ” in the text box and click OK Open run and type regedit and click OK
  2. Select Yes for the User Account Control popup window
  3. Now go to the following path: HKEY_LOCALMACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\
  4. Find the “ CCleaner ” entry in the list
  5. Right-click on it, then select “ Delete ” and confirm Yes Deleting CCleaner from registry editor
  6. Now close the regedit and go open the CCleaner

For those who are unable to open “ regedit ” just like the CCleaner, check the method for that below.

If Registry Editor “regedit” is also not opening, try this:

  1. Go to your “ regedit ” file path in your system: C:\Windows\System32
  2. Scroll down and find the file “ regedit32.exe “, then right-click and copy it Copying the regedit file from system32 to Desktop
  3. Paste it on “ Desktop “, then right-click the file and select Rename
  4. You can rename the file to anything you want Renaming the regedit file after copied to the desktop
  5. Now run the “ regedit ” file and follow the steps of the solution

For some least users, they might get the error “ You require permission from TrustedInstaller to make changes to this file ” when they will try to rename the file. Then you can check our guide about that here . Or you can run “ adwcleaner ” and “ Malwarebytes ” which will find the conflicts and you will be able to run regedit after that.

How to Fix “Printer is in an error state” Issue?

The error “ WinRAR Error: Next Volume Is Required ” usually appears when you’re extracting a multi-part RAR archive and WinRAR can’t find (or can’t correctly identify) the next file in the sequence . This often happens when a volume is missing , stored in a different folder , or renamed in a way that breaks the archive’s expected order .

Fix: CCleaner won’t Open - 2

In this guide, we’ll go over the most reliable fixes confirmed by affected users, along with what each method is doing behind the scenes so you can choose the right one for your situation.

Important: To extract multi-volume archives, you should always start extraction from the first file in the set. This is usually file.part1.rar , or (in older sets) the main .rar file that comes before .r01 , .r02 , and so on.

1. Download and Place the Missing RAR File

WinRAR needs all parts of a multi-volume archive to complete extraction. This error usually appears when one of the volumes in a set like .part2.rar , .r01 , .r02 , .001 , and similar naming formats is missing . Downloading the missing volume and placing it in the same folder as the other parts allows WinRAR to continue extracting normally .

  1. Look at the error message or review the list of archive parts in the folder.
  2. Identify which volume is missing (for example, part2.rar , .r02 , .001 , etc.).
  3. Go back to the website or source where you downloaded the archive.
  4. Locate and download the exact missing file using the same naming format as the others.
  5. Make sure the new file name matches the pattern of the rest. Example: If you have file.part1.rar and file.part3.rar , the missing one must be file.part2.rar .
  6. Move the downloaded missing volume into the same folder as the other archive parts.
  7. Confirm that all parts are in a single folder before extracting.
  8. Right-click the first file in the series (usually part1 or the main .rar file) and select Extract Here or Extract to Folder .
  9. WinRAR should now detect all volumes and continue extraction normally .

2. Manually Browse & Select the Next Volume

Use this method only if the next volume already exists , but WinRAR is failing to detect it automatically. This can happen due to incorrect naming , the file being in a different location , or a temporary file access issue. Manually browsing helps WinRAR locate the correct volume and resume extraction without interruption .

  1. Right-click the first file in the series (usually .rar or part1.rar ) and select Extract Here or Extract to Folder .
  2. When WinRAR cannot find the next volume, it will show the “ Next Volume Is Required ” message.
  3. A small window will appear, allowing you to manually select the next volume .
  4. Use the file explorer window to locate the folder where the other archive parts are saved.
  5. Select the next part based on the naming order (example: select file.part2.rar after file.part1.rar ).
  6. Make sure the selected file matches the naming format of the archive (no extra characters like (1) and no mismatched numbering).
  7. WinRAR will resume extraction using the selected volume .
  8. If additional volumes are missing or stored separately, WinRAR may prompt you again. Repeat the same process until extraction completes.

3. Rename the RAR files in Order

WinRAR relies on a proper naming sequence (such as file.part1.rar , file.part2.rar , file.part3.rar ) to extract multi-volume archives. If a file is named incorrectly, contains extra characters, or is out of order, WinRAR may fail to locate the next volume and show this error. Renaming the files correctly helps WinRAR follow the sequence and extract the archive without interruptions .

Note: Renaming only changes the file name , not the file contents. The goal is to restore the correct sequence so WinRAR can detect the next volume.

  1. Go to the folder where all the RAR files are saved.
  2. Make sure all parts of the archive are present and stored in the same folder .
  3. Check how the parts are currently named . Common patterns include:
file.part1.rar, file.part2.rar, file.part3.rar
file.rar, file.r01, file.r02, file.r03
  1. Look for files that don’t match the expected numbering pattern (for example, file.part01.rar , file.part1(1).rar , or unrelated names).
  2. Rename each file so it follows the same order without extra characters or mismatched numbering. Example:
Incorrect: file.part1.rar, file.part3.rar, file.part2(1).rar
Correct: file.part1.rar, file.part2.rar, file.part3.rar
  1. Make sure the text before the number is exactly the same for all files.
  2. Only the last part number should change.
  3. Right-click the first file in the series (usually part1.rar or the main .rar file) and select Extract Here .
  4. WinRAR should now recognize the sequence and continue extraction normally .

If you still get the same prompt: the archive set is likely incomplete (a part was never downloaded or was removed), or one of the volumes is corrupt and must be re-downloaded from the original source.
