Hi Jays,

you cannot limit the installer to run only on certain dates.

But you can limit the lifetime of your app by using something like this:
- count number of executions
- check system time
- check accurate time by internet (if available)
- save those values in (hidden) files or registry keys
- use a password to limit users/lifetime

You can do all this in software - but you have to make your own thoughts on this...

Hi Jays,

just a crosslink to a (very) similar thread

hi

thnx for the hints..........

but when u take system time into consideration the application will start running when u change the system time to the past.--rt?

limiting no. of iterations looks  simple but i want my installer to be rich at the same time i dont know how to use the register keys or internet time to consider.

can any one post a reply

thnx in advance

Hi jays,

some comments:
"when u change the system time": to protect software from misuse is always complicated Make some complicated algorithm
"i dont know how to use the register keys or internet time":
-registry keys: there are examples coming with LabView!
-internet time: look for NTP in the forum! (maybe here?)

Hey, you want to protect your software, so you have to write some protection routines.
Or ask a software consultant and buy those routines... There are also hardware solutions available - at a reasonable price
