Missing DLL file

[Guest]

Everytime I run a program on my hard drive i always get an error message
about a missing VBRUN400.DLL file. How can i get a copy of the missing
VBRUN400.DLL file? Also, i have a VBRUN300.DLL file on my computer. can I use
it instead?

VBRUN stands for Visual Basic Runtime. Visual Basic came in versions
1,2,3,4,5,6; so any runtimes you need will also come as VBRUN100, 220, etc.

Do a Google search on VB RUN or Visual Basic Runtimes and you should find a
download source. Should also be on the Microsoft download page somewhere.

This is the run-time file needed for programs written in Visual
Basic 4. I assume you don't mean that you get this message for
every program, but just a particular one.

How can i get a copy of
the missing VBRUN400.DLL file?

It's widely available for download. A google search will find you
many places to download it.

Also, i have a VBRUN300.DLL file on my
computer. can I use it instead?

No. That's for programs written in Visual Basic 3. You need both
if you have programs written in each.

Best to get it directly from the source:

http://download.microsoft.com/download/vb40ent/sample27/1/w9xnt4/en-us/vb4run.exe

And no, VBRun300 won't do. The application is specifically looking for features that were introduced in VB4. The VB5 and/or VB6 runtimes might be backward compatible, as well.

Doug, they're all separate. There is neither forward nor backward
compatibility in any of the VBRUNnnn files.

I'd have to disagree with that, Ken, on some level. I have found programs that were built with the VB6 runtimes referenced, but they ran fine on a Win2K machine that only had the VB5 runtimes. That tells me that many of the "functions" that exist in later versions, exist in ealier versions, as well.

Thanks, Doug. Interesting! I've never run across that, and as far
as I know, they are not supposed to be compatible.

Perhaps despite what's supposed to happen, there is sometimes
compatibility using certain programs, but not others.
