does registry need to be changed to grant permission to a program?

i have made a game and it's self installer after the game is installed it runs only if it is installed on e drive or d drive not in the c drive that has my os it says access denied somebody told me that it needs permissions by making registry changes is it so? i know how make the changes but what changes do i make??

Edited to add the text from the answer made by the person who create开发者_开发问答d the question:

i was writing to c:\programfiles\abess\ and the installer runs successfully the installed program does not run ,i am using windows 7 home and using administrator account

Is it trying to write any files to C:\ on a Windows 7 (or possibly Vista) machine? If so, by default you won't have write permissions there (assuming the C: is the system drive). Make sure that your app writes any files to subdirectories of C:\, like C:\Temp\ or similar.

I'm fairly certain that if it works on D: but not on C: it won't be a problem with the registry.

i was writing to c:\programfiles\abess\ and the installer runs successfully the installed program does not run ,i am using windows 7 home and using administrator account after installing if the program is run as "run as administrator" it runs successfully i am making the installer i can't be sure if on the other end user installs on c:\programfiles\ and gets frustrated when program does not run
