The 'another instance of SomeApp is currently closing..' error message can be frustrating, especially when you're trying to use a portable application like PuTTY Portable. This error typically occurs when the system cannot find an open instance of the application, even if it's not running in the background.

This issue can cause problems with the functioning of your computer and may lead to data loss or corruption. Fortunately, there are steps you can take to resolve this problem.

💡 Why You Are Getting This Error

  • The primary reason for this error is a resource leak or a temporary file issue that prevents PuTTY Portable from closing properly. When an application is not properly closed, it may leave behind open connections, files, or other resources that the system cannot find.
  • Another possible cause is a conflict with another application or a corrupted system file.

🚀 How to Resolve This Issue

Resetting PuTTY Portable to its default settings

  1. Step 1: Close all instances of PuTTY Portable and any other applications using PuTTY.
  2. Step 2: Open Task Manager (Ctrl + Shift + Esc) and look for the 'Processes' tab. Find the process belonging to PuTTY Portable, right-click on it, and select 'End task'.
  3. Step 3: After ending the process, restart PuTTY Portable to ensure that all temporary files are deleted and the application is properly closed.

Checking for conflicts with other applications or system file corruption

  1. Step 1: Close all instances of PuTTY Portable and any other applications using PuTTY.
  2. Step 2: Open the 'System Configuration' utility (msconfig.exe) to check if there are any conflicting processes running in the background. Press Ctrl + Shift + Esc, then click on the 'Processes' tab and look for any suspicious processes. If you find one, right-click on it and select 'End task'.
  3. Step 3: If you suspect that a system file is corrupted, try running the System File Checker (SFC) tool to scan and fix any damaged files. Open Command Prompt as Administrator and type `sfc /scannow`.

💡 Conclusion

To resolve the 'another instance of SomeApp is currently closing..' error message, you can try resetting PuTTY Portable to its default settings or checking for conflicts with other applications or system file corruption. If the issue persists, consider seeking further assistance from a system administrator or IT professional.
