Problem in MSI Installation "run at admnistrtor"

Question

Hi

I have created a Installer MSI file for my client.

in my application, we used trial version and license version.

to maintain the trial version-  I have created a hidden file in the location " c:\windows\System32\file.doc" at the first time run the application after the MSI installed.

my problem is, when client has Installed the application, and click the application Icon, they have got a error message "run at administrator" .

i have tested this error some system and after right click and select the option 'run at administrator' and application has been working properly.  

so Please help me, what will i do, run this application every where without "run at administrator" option.

Note:- in my pointview, this problem has arised to create a file "c:\windows\System32\file.doc" in this location.so i have changed this location but problem is remain same

Plesae help me

 

Thanks In advance

Answer 1

If your application wants to create a file in the system32 folder, it needs administrator permissions. Change the file location to a place where the user has write permissions, then it should work without admin rights.

Now I'm not sure if you problem is that your application shows the user account control (UAC) dialog to request admin rights and you want to get rid of this, or if your application does not show this dialog but you want it to show.

hi

thanks for the reply

in my requirement - if user trial period has expired then this hidden file is exist there,

so when user want to uninstall the application and try to use the trial period of this application so this hidden file restrict the use of application.

so user not able to re-use the software .

and "c:/windows/system32" folder is secure place to hide the file.

 

Thanks

Hi Dipendra,

>a error message "run at administrator" 

Is it a error or the dialog which requests for admin rights?

>in my pointview, this problem has arised to create a file "c:\windows\System32\file.doc" in this location.so i have changed this location but problem is remain same

If that can not solve your problem, I think it is not the problem of the file's location. Is there some code in your project that needs admin rights?

Sincerely,

>a error message "run at administrator" 

it is the dialog which requests for admin rights.

>in my pointview, this problem has arised to create a file "c:\windows\System32\file.doc" in this location.

my code is correct, its work fine but problem arise

when user have not admin right and try to install the MSI and MSI try to create file in "c:\windows\System32\file.doc" this location. 

my aim is :- i want to create a file in this location "c:\windows\System32\file.doc" and after creation i want to read this file through my Program  either i have admin right or not.

Thanks

Hi Dipendra,

Yup, if the user has no right , he will not able to access "c:\..". So how about creating your file in the other disk like "d:\" or "e:\".
