Installing software by Group Policy

I’m running a Windows 2000 Server and there are several Windows 2000 Pro and XP client workstations. I created a MSI file to install softwares on my all clients though Group Policy. When I rebooted one PC, software installed ok. But when I tried on some more computers but it wont worked. I found a message in Event Viewer saying it is unable to write to a registry key.

These PCs shows a message that the software is installing at the time of boot up but nothing happens. Where am I making mistake? It installed fine on first computer but not installing on any other. Please help.

Hello pmela, can you just tell me whether your client’s on which you are not able to install the software are both Windows 200 and XP OR any one of them? To me it sounds like there is some problem with the permissions. Anyways, until you reply let me tell you that you can also try deploying the software manually by running the msi as the system account and then see what errors you get. Let me know the results.

Thanks for your help Patter, you are correct. Even i had a doubt about permission problems. But still i'm not able to understand that why on
absolutely identical machines it will work on one but not the other. There
is also a mixture of XP and 2000 PCs. I have installed the MSI on the machine locally and that works ok. Anyways, help appreciated.
