My system is Windows 7, 64-bit. Recently I tried to install some Weather Channel desktop app on my wife's user account. The installer said I was missing two .dll files.

I ran a system scan and it didn't indicate any problems.

My question is, are those .dll files missing because of some corrupion or error, or should .dll's always be provided in the app "package"?

Which DLL's did it say it was missing? Could be expecting .NET framework (or a specific version), or perhaps C++ or VB run-times, etc. – Ƭᴇcʜιᴇ007 Jul 25 '11 at 21:48
I'll have to take a look tonight. I actually dl'd them and copied them to the system folder. – Lil' Smokey Jul 26 '11 at 15:10
If you just downloaded and copied them into place, then you may still have to register them with the system using regsvr32 or alike. – Ƭᴇcʜιᴇ007 Jul 26 '11 at 15:13
Sure, but does the fact that they were missing indicate a lack of integrity in the system? – Lil' Smokey Aug 5 '11 at 22:21
You haven't told us which DLL's, nor cleared up how you replaced them, so it's hard to make any kind of guesses. If it was one of the common runtime/framework packages from MS, and you successfully installed it via normal methods, you should be fine. :) – Ƭᴇcʜιᴇ007 Aug 5 '11 at 23:17

The .NET Framework 3.5 is included with Windows 7.

If you in fact downloaded whatever missing files were given to you in the error message, this will either:

1) Work fine after you register them like such:

Press Meta+R (Windows key + R) to bring up the run dialog box, type in "regsvr32 c:\whereveryouputthedllfiles"


2) Fail because they are the wrong versions of the file.

Strangely enough, it the install went through just fine. The app is crap so I deleted it. – Lil' Smokey Aug 5 '11 at 22:21
