How to open LabVIEW 7.x to 2012?

[NiCoder]

How can I open the LabVIEW 7.X by LabVIEW 2012?  I tried but it failed.  Can I install both versions on the same machine?

Explain exactly what you mean. A VI created with 7.x can be opened by all newer versions of LabVIEW. What 'failed'?

And, you can have multiple versions installed on the same pc but you will have problems installing drivers that are compatible with something so old and a recent version.

Please make sure that LV 2012 has the same toolkits/modules installed as you had for LV 7.x. Also driver APIs might be a source for "fails".
