Install 6.1 development environment after 7.0/7.1?

[Matthew_Williams]

I would like to re-install the 6.1 Prof. Dev. system to create a small app targeted for a Win98 machine.  Will this break anything in the
existing 7.0 or 7.1 environments?  Is there a better way?  Unfortunately the target is unique hardware and a newer OS is not
available.  Thanks.

Hi

I have this unfortunate situation as you did. I actually have LV 7.1, LV7.0 and LV6.1 all on my pc. just remember that the VI will be opened with whichever version was last used if you click on it. so if you accidentally opened a VI intended to run on ver 6.1 for example with ver 7.1 and saved it, you will not be able to open it with 6.1 again.

There is definitely no problem with having multiple versions on the same computer, and I can't say I see any reason why installing an older version would mess things up (although I do seem to remember seeing something along those lines recently. Try to search for it).

One point - 98 supports 7.0. Any reason not to build the app in 7.0?

Since you are only installing the pure development environment, you shouldn't have any problems. If you were installing drivers and and toolkits, you may run into problems, but since you aren't, you should be good to go.

Just do a Custom Install of 6.1 and be sure to unselect to install the drivers. You'll need to reinstall what ever driver versions you currently have installed to get them installed to 6.1.

You can run multiple versions and select which version you want to open when you double click a VI by adding the following line to your LabVIEW.ini file of the version you don't want to open on double click.

"RegisterExtensions=FALSE"

Matt,

I would suggest installing it in a National Instruments1 or National Instrument_6.1 directory instead of the National Instruments directory.  I have done this in the past and had 3 versions on the same machine.  Hope this helps.

Thanks for the input everyone.  I think I'll go the 7.0 route; didn't realize that it could still target 98.  I'll
keep the other ideas in mind because I expect 6.1 will become an issue at some point.  Thanks.
