Solution 21990: Installing More than One TI-Nspire™ Family Software to the Same Location Causes the First Installation Not to Work.
After I've installed two or more of the TI-Nspire family software to the same location, why won't one of them work but the other will?
The TI-Nspire family software contain some of the same common components. It should be noted, however, that due to the nature of the software, the files, while named the same, will have slight variations. If more than one TI-Nspire family software are installed to the same location, the first installed will not work, as some of its files will be overwritten by the second.
To avoid this situation, please ensure that the TI-Nspire family software are installed to separate directories.
