Tally 7.2 not working in windows 7

Since last few days I am trying to install full version of Tally 7.2 in Windows 7 but everytime after installation it is not getting opened. Anybody any idea about reasons of the same.

Further, I also tried to install Tally 9 in same windows version but I am not getting the patch/crack of tally 9 to install the full version of tally 9. So, can anybody throw some light on this issue also?

Hi

I was also facing the same problem regarding Tally 7.2 and now i've stopped searching for the solution since i came across this blogpost from Microsoft which states that Tally 7.2 is incompatible with Windows 7 and hence shall not run on it. You can have a look at the same:
