request admin privileges + run upon finish

lerklompen · 21st January 2010, 11:44

when running the installed program upon finish in combination with requesting application privileges as admin:
- if a "user" is trying to install, he/she must choose one of the "admin" user accounts to be able to install.
- the password for this admin user must be filled in to allow the install procedure.
- upon finishing the installation the installed program is started:
this process is actually started as the admin user, but running on the logged on user's desktop!
if the application has any kind of file dialogs (open, save as, etc.) this "user" is now able to browse, alter, delete, all of this admin user's files!

this "bug" or what to call it, is fairly common among many installers, but it would be nice to be able to avoid it.

is there any workaround? that is; let the installer start the program upon finish, but as the user logged on, not as the admin running the installation?

Two solutions exist for NSIS:
1) Remove the Run Application checkbox from your finish page. This is the simple solution.
2) Use the UAC plugin to execute your application As User in a finishpage run-function. This is the complicated solution, and sports a much higher chance of going wrong.

Option 1 is recommended. The Run checkbox is practically useless anyway.
