Adobe CS3 Installer

If you get this error with the Adobe CS3 installer, here's the fixe:
Please insert Adobe CS3 Master Collection D1 into drive to continue installation.
Start regedit, and use the search function to look for "CS3\Adobe CS3\payloads\." Every time you find it, replace it what comes before it (d:\) with the new drive.

Multiple Certificate Authorities on OpenVPN

I lost the CA key for an OpenVPN server I have. Not wanting to modify the configuration on an existing client, possibly taking it down, I realized I just need to use two certificate authorities. At first, I tried putting two CAs in the configuration file, but nothing. Then, I read that the both certificates just have to be in the same file, so the ca.crt file just has two certificates in it.


That was it. Then, I just had to make sure new clients get the double certificate file, as the server's key was signed by the lost CA key.

OpenVPN and Vista (32 and 64 bit)

Since OpenVPN creates a network interface, it needs essentially a software-backed network driver. Linux uses tun and tap drivers. Windows also uses a tap driver, but it's provided by the OpenVPN project. Back with Windows XP, this wasn't an issue; all installing an unsigned 3rd party required was clicking a "Continue" button. Vista doesn't allow this; it requires signed drivers, but a new certificate authority can be installed, though the process isn't for end users.

Luckily, starting with OpenVPN 2.1, OpenVPN has signed drivers for both 32 and 64 bit versions of Vista. The only headache is noticing that the download page lists the 2.1, a release candidate, between the latest stable version and legacy versions.

Bad sectors on CDs

I had a CD image generate by Clone CD with some corrupted files, but I also had good versions of the files. Instead of extracting the files and making a new ISO, I decided to try to fix the original image.
