My computer tells me that I must have: C:\PIPEPLUS\UTIL\LVIEWPRO.EXE
Tto execute some programs. What is it?

LVIEWPRO.EXE is the executable file of a graphics viewer and editor
program for Windows.

More information about Lview Pro may be found at the Lview website:

Lview
http://www.lview.com/index800.htm

You can download an evaluation version of Lview Pro 2002 from either
of these sites, or from Lview's site (linked above).

Tucows
http://tucowsthemes.tiscali.dk/editors/preview/58368.html

Voodoo Files
http://www.voodoofiles.com/548

You will need to have 9,248,768 bytes free on your hard disk in order
to download this program.

I downloaded Lview Pro from Voodoo Files and have verified that the
executable file is indeed named LVIEWPRO.EXE.

Search terms used:

"lviewpro.exe"
"lviewpro"
"lview pro"
"lview pro" + "download"

I hope this helps. If anything is unclear, or if a link does not
function, please request clarification; I'll be glad to offer further
assistance before you rate my answer.

Scan the file/folder for virus before executing it.  Some hackers
plant virus into recognizable filenames, like LVIEWPRO.EXE.
