Nuendo 5.1.1 Update crash

When I try to install the 5.1.1 update it crashes and dosn’t work.
My previous version is 5.1 with Win7 pro 64bit.
It too doesn’t work when I call the update as administrator.

Any suggestions?

It seems that you updated the installer, because the version I have downloaded was from 5:11pm the “new” version is from 6:04pm. The “new” version worked for me.

no problem here N5 32bit / Win 7 x64.
