You can store the install date somewhere in your application's registry or in database and then compare that date every time you lunch your application.If it crosses more than 30 days, then you can get your requirement done.

I think this is a good question to start with.

Here is an excellent article[^] if you want to learn regarding building trial versions of software. It covers:
Where to Store the Expiration Data
How to detect system clock manipulation

You may also want to read another piece[^] from the same author to broaden your knowledge.

Finally, some SO discussions such as this[^] may also help.

This question is TWO YEARS old and your solution isn't applicable to the problem and is very easily worked around.

Don't post answers to questions this old.
