I was using VSD on my new Vista 64 os and it worked fine. Then it would not open up.

I deleted it then re downloaded, and it was again working fine.

Then just now, it would not open up again and continually says:

Visual Site desginer has stopped working.

Well.. um ...err, it won't open up to work.

Help!

Try right clicking on the VSD Icon and select run as administrator. Even if you are logged in as an administrator, VISTA wants to be sure you do not run any program it deems unworthy unless you select run as administrator.

If that does not work, there are other folks here that know some other VISTA tricks.
