Cannot Install LV Runtime Engine 7.1

Cannot Install LV Runtime Engine 7.1

Post by maroone » Wed, 23 Nov 2005 23:40:46


Some of our users are having unusual installatiion problems while
installing the LV runtime Engine 7.1.1 on win2k. Our users have
installed another application recently and in that process the LV
runtime engine was removed from their computer. So, they tried to
install the runtime engine(downloaded it from NI website) again but couldn't becuase they keep getting
the message that they are not logged in as administrator. We logged in
as admnistrator and  tried installing the runtime engine again,
but the error keeps occuring and is not allowing us to install. I
searched the NI discussion forums and the Knowledge base to find
answers but did not see any that match our problem. From some of the
posts I suspect it has got something to do with Microsoft hotfixes and
windows upgrades etc.

If anyone else had seen this kind of behavior and has found a fix,
please share it with us. Any help will be greatly appreciated.

Thanks Ahead

Do you know what program/applciation it is that was installed?? 
Is it a LabVIEW program or some windows program??  I have been
trying to recreate the problem on my 2k machine, but have been
unsuccessful so far, and it would help to know what app caused the
problem, if it is known.

I ran a program I created in 7.1.1 and then installed another program
that I created in 8 (both stand alone .exe files with the runtime for
each included) and I was able to run either program with no
issues.  If you want I can give you a list of the updates that I
have installed on my machine from Microsoft if that will help your
debugging, since you thought it was a hotfix.

Hello Kevin,

It was a windows program. We were running that program along with our daq application written in LV.

I sitill cannot find any explanation what could have happened when we
removed the program. Maybe something was removed from the registry but
seeing the message to login as administrator and run the install is
what's confusing to me.

This is an unusual problem.  I would first go through the add/remove
programs through control panel.  Loate the "National Instruments
Software" item and select "change".  See if any LabVIEW
components are there and slect to remove them. This will completely remove the
LabVIEW components.  Then attempt a reinstall of the runtime engine. 
If this still causes problems, you may have deleted the old LabVIEW runtime
engine in an unusual way which is interfering with later installs.  If this
is the case, there are some other methods that we might be able to use to
uninstall fragments of NI software.  Removing the software does not fix
the problem post back and let us know!

Could you please tell me if you know any other methods to completely
remove the LV runtime engine, other than using the regular uninstall
and Add/remove programs functionality from Contorl panel?
