error 1026 invalid reference pops up only on one computer out of 5 similar win 7 laptops

[freemason]

Hello,

I am having a weird issue.

i have an exe built which calls each dynamic VIs and loads into subpanel for each button.

i have given this exe for beta testing to 5 people internally and all the systems are configured similarly. it works fine on all for just one one computer this error pops up and only for the 1st dynamic VI call, rest of the buttons calling other subVI into subpanel is working fine. 

I donot understand how the same program works on all but one. what should i be looking for?

the buttons to call subVI are in a cluster and each button call generates a path for the invoke node.

is it any windows 7 issue?

Plz help

Can you show the code? Any external code being called? Anything at all unusual about the application or the PC where it is having problems?
