Open labview versions till 7.x with 8.5

Question

I've update my labview version for 8.5. Uninstalling the previous version in other to avoid some complications in the future that can be caused by the mix of versions (that's what I think).
But the first problem that I've found it's that I can open vi's made on versions till 7.x.
In this specific case. i can't open the labview_win_util32.zip.
How can I turn around this problem without installing old versions of labview?

Hi Jorge,
That's an interesting problem that you posted... Glad you found a solution.
As for multiple LV installations, I have on one PC LV7.0, LV7.1, LV8.2 and LV8.5.  Furthermore, you can open different releases at the same time (ie: work on both LV7.1 & 8.2 at the same time).  They do not seem to interfere with one another and I think that it's rather common to have multiple installs. So theres really no need to remove a past installation when upgrading to a new (major) release..
