AFAIU you're using winGRASS standalone installer. Correct? Which Version?

winGRASS standalone bundles its own python version.

here it seems to point to an external python living in C:\PYTHON26.

Have you more python version installed on your Windows System?

these several python installations may interfere. 

Could you rename C:\PYTHON26 to e.g. C:\xxxxPYTHON26 and try to restart
winGRASS and post the results here?
