Remove legacy client and install 0.9.5 client

[Wayne Workman]

@johnomaz I was planning on doing something similar to what you did, and my plan always involves using msiexec and product codes

@johnomaz , a couple quick notes:

1. Handlers.dll will not exist in newer version of the client, FOGService.exe is the safest file to check for.
2. Any setting you see in the MSI can be set via CLI arguments. For example, to set the server address, just append WEBADDRESS=“x.x.x” to the install command.

@Jbob I used Handlers.dll because it doesn’t exist with the legacy client install. If in the next version of the client it doesn’t exist, I’ll change the argument to look for a different file. FOGService.exe exists for all versions so it would never uninstall if it found the file on the legacy install.

@johnomaz ,the next version should automatically remove the legacy client:

Do you mean the next SVN or the next version of the client (0.9.6?).

[Joe Schmitt]

Version of the client.

1. Open a command prompt as Administrator.
2. Type wmic and hit enter.
3. /node:“Computer-01”,“Computer-02”,“Computer-03” /user:domain\user /password:password product where name=“FOG Service” call uninstall /nointeractive
4. From there you can deploy the new client

@d4rk3 While a valid solution, it’s not all that easy to accomplish when you have 500 to 6,000 hosts…

[d4rk3]

@Wayne-Workman Other than waiting for v0.9.6/re-imaging are there any easy ways to accomplish this on a large amount of hosts?

[Joe Schmitt]

@d4rk3 Snapins. If you are smart about forking processes you could use a snapin to upgrade the client.

[Wayne Workman]

@d4rk3 Or if your clients are bound to Active Directory, you can use a simple startup script similar to what is in the first post.

I’ve already upgraded all of my clients, I was just genuinely curious to know if any easier methods existed
