Winblows Environment Variables

post #1 of 5

Thread Starter 
Ok, I have bzip2 for Windows and I wanted to make my own WinRAR SFX installer. That's the easy part.

I want to have a batch file or script of some-sort to permanently modify the PATH variable to append %systemdrive%\\bzip2\\bin on the end of it.

Everything I've half-assed researched brought up doing it manually in the sysdm.cpl or using set PATH=%PATH%;%systemdrive%\\bzip2\\bin which only stays useful for the current cli session.

Any help would be greatly appreciated.

Hi,

I know you can do it within Windows using code but if you want to use a batch file then you can use the setx.exe utility. I think (from memory) it came with the resource kit but I am reasonably sure it can be downloaded (feel free to correct me here). Also, I think it can be done with kixtart, or a vbs script. If nobody else can answer it off the top of their head I am sure I can track something down in one of the other languages . . .

Take care

Rhys

Right click on "my computer", go to "properties", go to "advanced", go to "environment variables", and add the appropriate variable.

EDIT: oho, it has to be automated. ignore this post.

You need to change a registry key. The PATH is stored in HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Con trol\\Session Manager\\Environment\\Path. If you want the change to take effect immediately without a reboot, then you need to send a WM_SETTINGCHANGED Windows API message to the system to tell it to reread the registry.

I found some Delphi code on the web that explains the process, I'm sure you can translate it into whatever language you are using.

Wow. I was kinda lost by that, so I downloaded a trial of Wise for Windows Installer and made a MSI installer package.

Thanks for the info.
