[BUG] Cannot change install location in official 10.2.0 Windows installer

[stewboy]

Describe the bug
When running the 10.2.0 installer on Windows, the installer offered no option to change the install path. This was a problem for me because the default install location was on a drive letter that I no longer had a drive mapped to. On trying to install there, I got the error 'The drive or UNC share you selected does not exist or is not accessible. Please select another.' The installer then quit, offering no option to change the drive or path. I had to temporarily map a drive to that letter to install it, then change it back - I only noticed just now that I also had the option to download a .zip file instead.

Build that the bug occurred in
10.2.0

To Reproduce
Run the installer.

Expected behavior
I expected at some point to be able to change the install location.

Hi @stewboy, are you saying you don't see this browse button next to the path? I just tested with both user-level and admin and am able to select path in both instances.

This occurs when you are upgrading from a previously installed version of Odamex. It will upgrade to the same location and also keep the same type of install (user-permission Programs vs admin-permission Program Files).

If you want to change the location or installation type, please uninstall Odamex, then reinstall it. This is a limitation of InnoSetup and although I've hacked on the installer before, I don't know that you can bypass that limitation easily.
