You risk a visit from the GCC police for posting in the WRONG forum! ;)

But, yes, if you read the release announcement of 20070525 it does recommend uninstalling the previous version first.

WinAVR, yes. AVRStudio (as the OP asked), no.

To reiterate, do uninstall WinAVR before installing the new WinAVR, but there is no need to uninstall AVRStudio 4.13 (which you indicated you have) before installing WinAVR 20070525.

There is very little coupling between WinAVR and AVR Studio. You should be able to install/uninstall/reinstall either AVR Studio or WinAVR independently of one another.

With the latest release of WinAVR, 20070525, I would highly recommend that you uninstall any previous version of WinAVR. The reason why is that the Registry keys that are installed with the new release, have different locations and names and are designed for future coexistence with other versions of the AVR toolchain or other toolchains. But to do this, the automatic uninstall feature (during installation of new version) has been removed.
