Windows 10: How do I find out what program is calling a .dll file on startup?

My neice had a virus which I successfully cleaned out, but now every time I start up the laptop I get an error message that it couldn't load "C:\Users\her name\AppData\Local\Call Kit\CallKit.dll" and I am having a real trial with attempting t identify what program is calling for the absent .dll file. Any suggestions would be greatly appreciated!

RunDLL (Please Help!)

rsx7.dll is not a known common dll file and the path (C:\p07L......) is not a recognised program directory. Pseudo-random directory names are sometimes generated by update installers to unpack the files but the path and dll being unrecognised I would be
suspicious of the file's origin.

1st check the C:\ drive to see if the directory exists, if it does look at the contents to try and establish what is in it.

Check task manager > Start-up for unknown entries. Try disabling some to see if the error goes.

Then search the registry for rsx7.dll (do NOT make any changes) and see if you can find what program is calling it.

 

Where do I find a .dll file?

Hi Jeanne

Click the link below to download Visual c++ redistributable 2013, install that and restart your PC to fix this issue . . .

You could download Autoruns for Windows

It will tell you everything that is called on startup and from where.

 

You could unregister the .dll if you want, here is how:

Unregister and Re-register a.. .dll or .ocx file and delete them

One has to be careful with dll files in case they are shared. try renaming it first from ProgramName.dll to ProgramName.old-- and run your system awhile to see if you get any warnings first, especially at boot up. Then when no problems appear or crashes show up in Reliability History(in the Action Center) then you can unregister the dll.

Open an Admin command prompt by right clicking the windows icon and choose it.

For the path name you can use drag and drop in windows 8 by opening file explorer and dragging the dll to the command prompt after you type regsvr32 /u"For example:
regsvr32 /u "C:\Windows\System32\amdmantle64.dll" (this is for an AMD ´graphics dll)
Don't forget the quotes

Registering a dll file

To register a dll or ocx file, open a command prompt windows as an administrator, type the following and hit Enter: regsvr32 “path & filename of dll or ocx“
Unregistering a dll file:

To un-register a dll or ocx file, open a command prompt windows as an administrator, type the following and hit Enter: regsvr32 /u “path & filename of dll or ocx“

This will register or unregister the dll file.

 

Thanks a million halasz - That program is the bomb! Wish I had it for the last 5 years or so, would have sped up quite a few repairs!
