Hello Ebenezer,
To my knowledge, we have not tested any version of CVI on a tablet PC (7.0 or otherwise). Thus, I cannot say that we *officially* support it. However, I do not see any reason why 7.0 would not work -- either as a development environment or as an executable. I would imagine, however, that writing C code would be difficult on a tablet PC unless you have some kind of keyboard.
I search around for other customers that my have used CVI on a tablet PC, but I didn't find too much. Nonetheless, you may want to take a look at this thread:
Perhaps they have some more insight/experience? Hope this helps,
