SOLVED Problem with Postallchthyisms.dll

[judhistira]

Hello guys,
After loading process of my Windows 10 finish, there is always a dialogue box with a message like this one:

There was a problem starting Postallchthyisms.dll
The specified module could not be found

I don't know the effect of this missing .dll, but it is annoying.
Could anybody help to resolve this thing?
Thank you in advance.

Hi judhistira,

Whatever that DLL is, its not part of the Windows 10 OS. Thus it must belong to a third party application you have installed at some stage.

You could right-click on Start then left-click on Task Manager. When Task Manager opens click the Startup tab and take a look at what is listed there as these are the applications which can load as computer boots up.

You could disable the culprit there if it's obvious which one belongs to your mystery DLL file.

Alternatively, a third party application may have written a registry value to force its automatic boot when computer starts. If you have all ready removed a virus, or some third party application using uninstall, a security program, or some cleaning program, this value may have been left behind, and it is called, but as the error tells you, there is no module for Windows to locate; thus its unable to load.

For a local User the common registry keys to check are:

• HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
• HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce

If this issue is affecting multiple Users on your computer then its more likely to be here:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce

To save opening the Registry Editor immediately you can do a simple reg query via a standard command prompt:

• Right-click on Start
• Left-click on Command Prompt
• When the Command Prompt window opens type or copy & paste the following commands.
  
  Note: Press Enter key after each command to execute
  
  

  reg query "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run"

  
  

  reg query "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce"

  
  

  reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run"

  
  

  reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce"

  
  Sample result image - your's may differ
  
  
  

If nothing shows up here there its possible it has created its own unique Registry key in which case you'd need to search the Registry for that key. Again, you could search the registry using command prompt like so:

• reg query HKCU /v "Postallchthyisms.dll" /s

• reg query HKLM /v "Postallchthyisms.dll" /s

  
  These are the likely keys to contain a new third party subkey which calls on that mystery DLL file. It could be written else where, but that is highly unlikely.
  
  Report back on your results. If you do find a reference to that Postallchthyisms.dll in the registry I'll tell you how to remove it and thus end this error message.
  
  If on the other hand, nothing shows up using the above commands and/or searches then you could make use of Microsoft's tool designed to dig out all startups called AutoRuns which you could use to help locate this too if needed. That can be downloaded via Microsoft's Technet site here:
  
  https://technet.microsoft.com/en-us/sysinternals/bb545021.aspx
  
  This takes a little getting used to using though, so if you end up needing this you may need help on using it. Just ask if you require assistance. Someone will help.

Big thanks,
Your advice has proven work!
The *.dll comes from uninstalled printer driver.

Thanks for the update. Glad it has helped you resolve your trouble.

Just remember if you have any Restore Points or you have created a System Image for backups, you will need to remove that call to the module from those too, otherwise you may see the error return should you use a restoration point.
