I've spent the day learning about .dll s! I finally found the copy of my missing one: js3250.dll. It belongs in Windows.
I found 2 different instructions of how to install.
1) said to go to Run and type in regsvr32js3250.dll and press OK.
Well, it says "cannot find ............... and to check for typos.
2) one said to copy it into Windows/System32/ then go to RUN. But I have no clue how to copy into that file path. I'm a computer dummy!
I did go and found the "system" folder and copied and pasted it there, but what do I do now?
