Follow the above steps for instealling gear but follow this last step before rebooting your PC. It won't permantly solve your problem as I've had to deal with it more than once, but it will provide the fix to allow itunes
to go back to normal. I found this somewhere so it's not not my resolution. I wish I could remember where I found it to give proper credit, but more people should know about this because even after doing all the registry changes and reinstalling GEAR, my itunes would not work until I did this.
• Good news!!!!I have had the same problem as you and have been dealing with it the last 2 days-uninstalling itunes,quicktime and then reinstalling and installing gearproduct download??Anyway to make a long story SHORT:
1. Do a search for a file -GEARAspiWDM.inf in C drive
2. Right click and install
3. Reboot the computer
4. itunes should be working without the error-I hope, it worked for me!!!!!!
good luck, K
