Don't worry about it.
Restart computer in Safe Mode (keep tapping F8 key, when computer starts to boot, until menu appears; select Safe Mode)
Find msimg32.dll file, I sent you, right click on it, click Copy
Open Windows Explorer. Navigate to C:\Windows\System
In right pane, scroll down to find your msimg32.dll file. Rename it to msimg32.old
Right click on System folder, click Paste. That will paste new msimg32.dll file into System folder.
Restart computer. See, if error will pop-up again.
P. S. Some .dll files can't be replaced in Safe Mode. In that case we'll have to use DOS.
