- Disable UAC entirely by going to Control Panel > User Accounts > User Accounts and disabling UAC. This will require a reboot and does lower the security level of your host -- so I suggest using it with caution as a way to troubleshoot only.
- Run MATLAB in an elevated session by starting it as Administrator. See if the issue persists.
GigE Vision Devices on Windows 7

Hi, I'm trying to install GigE Vision Devices on Windows 7 in Matlab 2010b for a Basler Ace series camera. I saw there was a bug in R2010b for GigE Vision Devices and I followed that also. But problem is to get the output from the camera. So i go through the troubleshooting - imaqhwinfo shows 'gige' adapter perfectly but imaqsupport is showing
??? Error using ==> imaqsupport at 63 Cannot open file for writing.
Why this kind of message is coming?
From 'Software Configuration' how can I check following files are installed properly in Windows 7?
GENICAM_CACHE_V2_0=C:\WINNT\Profiles\All Users\Application Data\GenICam\xml\cache
GENICAM_LOG_CONFIG_V2_0=C:\Program Files\GenICam_v2_0\log\config\DebugLogging.properties
GENICAM_ROOT_V2_0=C:\Program Files\GenICam_v2_0
Any kind of feedback will be appreciable.
Regards, Chotan

Do you have UAC enabled on the machine? Some of the locations in the environment variables mentioned above may not be writable by non-Admin users (or users who are not elevated). Some possible ways to troubleshoot:
If the above steps work, I think the most likely culprit is the GENICAM_CACHE_V2_0 variable, which is attempting to write under the OS install directory. The default location of user profiles in Windows has been moved outside of the OS install directory for a few releases to avoid this issue -- your profile directory is in the "old" location. The second place that may be causing problems is in the GENICAM_LOG_CONFIG_V2_0 variable, if something is trying to update that as a user. I believe that is also prohibited under UAC for "regular" users.
