i can't get it to run..
in version 0.0.5 and 0.0.6
windows just shows the process but the windows doesn't appear
running on Windows XP Pro SP2
Ran into the same problem after initially downloading GPU-Z. Upon running the executable, the process would show up in task manager, but no GPU-Z window would ever display. After dissecting and screwing with it for a while, I was finally able to get it working using the following steps:
1. Navigate to your temp directory (i.e. "%userprofile%\Local Settings\Temp" on XP) and delete any instances of gpu-z.sys you find. Assuming you have attempted to run the program before and run into the problem in question, you end up having to kill the GPU-Z process from task manager. This means that GPU-Z never gets to "clean up" the temp file(s) it creates, which, at least in my case, ends up causing problems when trying to run the program again ("Could not start driver: the system cannot find the file specified").
2. Temporarily disable your Anti-Virus software. For reference, mine was Kaspersky (KIS) 6.0.
3. Right-click the GPU-Z executable, select "Run As", and, if it is selected, un-check the "Protect my computer and data from unauthorized program activity" box.
4. For overkill, go to Control Panel > System > Advanced > Performance > Data Execution Prevention, select "Turn on DEP for all programs and services except those I select", and add GPU-Z to the exclusion list. You may (or may not... or may just want to disable DEP altogether) want to change this back to its default setting after running (assuming it works) GPU-Z.
5. Attempt to run GPU-Z again. If it returns the "Could not start driver" error, just close the box and try again. It
should work the second time around.
A semi-royal pain, I know, but, for what it's worth, I have managed to successfully use this workaround on two different machines that were experiencing the issue.
