New Nvidia drivers not compatible with Win7 Aero theme

I installed the new Nvidia Drivers gor my gt 610 from the 301 version to 306 version,when I installed theme it says the windows 7 aero theme is not compatible with these drivers. Is there any way I can revert back to the previous drivers to resolve this problem?

You should be able to roll back the driver to the previous driver by right clicking on Computer and going to Manage. When there, go to Device Manager and highlight the Nvidia component, which should be the display adapter. Right click and click on properties. You should be able to roll it back from here.

If you are not able to roll-back as allman71 said you can download the older driver.
GeForce R300 Driver - Version: 301.42 WHQL

Try to rollback and also try the new version(306.97). If downloading from Manufacturer site, Please read the details in their description and try to ensure that you are installing the suitable drivers for your chipset/graphic card
