For installing on Windows 7, you should be using Pervasive PSQL Summit v10.30, the only version certified for Win7. You can download a copy of this installer from the Pervasive web site here:
While you're at it, you may want to upgrade your other systems to v10.30, too, to take advantage of the latest bug fixes and updates. Note that v10.00 does have a slightly different license scheme than PSQLv10.10 and newer, so if you happen to have two stacked licenses, you'll need to convert one to a User Count Increase first. If your server has a single PSQLv10 license installed on it, then you should have no issues.
