dpinst problem when running in Vista non-administrator mode

[Galit Heller]

Hi,

I've encountered the following problem when attempting to run dpinst
(version 2.1.0.0) on Vista systems (both32 and 64 bit) w/o administrator
privileges:

The hourglass-circle flashes, task manager shows multiple instances of the
dpinst process, and memory utilization is high.
After approx 10 minutes (actually on 64 bits only reboot helped, after ~30
minutes), the processes disappear and the system returns to normal memoryand
cpu utilization. DPInst.log isn't created, driver isn't installed, and no
error message is shown - which poses a problem for the end user of the
installation package, which invokes dpinst as a custom action.

In XP, the same dpinst.exe program presents an appropriate error dialog
saying user does not have sufficient privileges to install.

Is this a know issue with dpinst ? Is there any workaround to eliminate the
issue ?

Thanks,
Galit
