Microsoft Dynamics CRM Server install failed.
Action Microsoft.Crm.Setup.Server.MsiInstallServerAction failed. This patch package could not be opened. Verify that the patch package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer patch package.
I was very close to completing the CRM v4.0 installation on the server during a client implementation when I received a dialog box just as one displayed below. I've done plenty of implementations before but never came across any such error during installation. It made me think for a while, what different did I do during this installation and I noticed it was the recommended update. (The first step during a CRM installation)
After a while of thought and reading the error over and over again, I thought let me try this.
I simply cleared the IE cache, increased the cache size to almost 2 GB and re-installed CRM from the beginning, including the recommended update during the installation steps. The CRM installation glided to finish.
A happy ending!
