Some user report error when trying to update an existing driver 0.9.x.x.Usually a message box pops up with a message like "Fatal Error during installation", or an error that installation was not possible.

Please uninstall the old driver before updating. If this does not fix the problem please execute the following steps and try again:

• Delete cifXDrv.sys from "Windows\system32\drivers" folder
• Delete cifX32dll.sys and cifXcpl.cpl from "Windows\system32" folder
• Search in "\Windows\INF" folder for all oem*.inf files belonging to the old cifX Device Driver. (This can be done by searching all files for the string "cifX")
• Delete all previously found OEM*.inf and OEM*.pnf files from the step above
• Delete INFCACHE.1 from "\Windows\INF" folder
• Uninstall all cifX devices using the device manager (Right-click on the cifX device and select "Uninstall...")
• Reboot and try re-installation after reboot

There seems to be a problem that Windows does not recognize the new driver if old INF files are still present.
